Well done !... I've Rv'd for~ 45+ years in all sorts of rigs. We ordered a 21' F350 7.3 Godzilla with 3.73 SRW. We tow a 30' tt weighing in at ~ 8200-8400#'s. We mostly travel around the Pacific N.W. up & down a fair number of hills. Last year at this time we did a 4k mile snow bird trip to AZ & back. We averaged 10.3 mpg. We had a couple of legs with big side winds and at times head winds. Got 6-6.5 on 2 of the short legs. As you stated, plenty of power and very good engine braking. I do keep it tow / haul mode but I do a lot of manual shifting going up or down hills. Usually running at about 2500 rpm or 3000-3400 going up the large or steep hills. Friend with a Duramax diesel was averaging ~ 1.5 mpg better. we run at ~60-62 mph. He also paid ~$9k more for the engine option + DEF + about $1 a gal more for fuel. He has more torque going up hills but I have no trouble keeping up. I'm very pleased with my choice.

I live in Utah. I took possession of my Godzilla in October of 21. It was the first production run off the line for 22. Not only is it my tow vehicle, but it is my daily driver. I ordered the crew cab XLT with the 8’ bed and the 3.73 rear axle ratio. I love it! Over the life if the vehicle I am getting 15.7 mpg. While towing I get 10 mpg. I tow an 8k lb trailer with two atv’s on a rack in the bed. Would buy this truck again without hesitation.

I live in CO and just got back from a trailer camping trip. Approx 9,000 lb 30’ Jayco trailer, probably with another 300 lbs in the bed. 2023 F350 diesel, CCSB. Obviously did well over the divide, but oil temps were concerning me a bit. 228 degrees during 65mph pulls up Vail pass and to the Eisenhower tunnel. Otherwise on normal conditions all temps around 190, 210 on the transmission.

Great review, thank you!

This is a great video with a ton of data points to consider. Great comparison and real life experience. Thank you.

Very detailed video! Those 7.3’s sure are in a class of their own.

New subscriber - thanks for the video. I am enjoying your channel and hearing about your journeys. I like the southern drawl, kinda relaxes me to listen to as my grandpa's family is all from Georgia and I enjoy their accent.

This is the best, most informative video on the 7.3L, 3.73, MPG. Thanks for sharing all that information. Very well done. Keep putting videos out.

Great info! We’ve been really happy towing with our new F350 with the 7.3. We’ve done several videos on the topic. Great truck! Your trip looks awesome.

Dream beard and truck.. one day I'll have the truck. Thanks for posting

thanks for the information i have a 2020 f 350 with 7.3 and 373 gears, going to south Dakota in may from Pittsburgh pulling a 32 foot 5 wheel

Great video thank you

Good video, very informative. First time I’ve ever heard about locking out the 2 higher gears

We bought our 7.3, 10sp, 4.3 rear end, Tremor almost two years ago now with 28k miles on it. 90% of the time, it has a 38ft bumper pull at 11.3k gross RV behind it. Been to Chicago and west coast twice, western states all over. Lifetime MPG says 8.3mph. Flat highway, 10th gear about 10.5mpg. 1-5 percent grade in mountains, truck putting in 5-20% effort. Rarely on the brakes! Truck is capable all over the place, looks good, and comfy.

Love the new Godzilla 7.3L V8 ..runs sweet in a '22 F250 . 👍🏻

I just bought a 2020 F250 STX 7.3 and tow a 5000lb travel trailer which has been a dream in the Colorado Rockies and averaged 11.2 mpg. I have seen my numbers down to 10.8 when driving over the mountains in Baja California with a head wind. And I would like a bigger camper but know the mpg is gonna drop but I rarely drive faster than 65 and usually keep it at 60 because I don’t need a ticket and not in a rush.

Great Review Love the 7.3. One of the biggest things I notice is that traveling west to east, tail wind, is always better than east to west, head wind.

Great video, this is exactly what we needed to see/know. I have a 22 F350 7.3 Godzilla with the 3.73 like you. I will be towing my 8,800 lb 30' travel trailer starting this summer. I was using my 08 F250 with the 6.4 powerstroke previously, so I felt the new gasser would do the job, but haven't experienced it yet. Funny you planned your family vaca around the daughter's softball tournament. We have been doing the same thing for years!

Great info on 7.3 and your trip I have a 2020 f350 7.3 with the 3.73 gears and love it, we have pulled our 40ft 5th wheel 14,500lbs. loaded over 4000 miles and avg has been 7mpg overall, the truck has 36,000 miles on it now.

There has been a few times I wish I would've ordered my truck and gotten the 3.73's instead buying the 3.55 that was on the lot, but so far it's done what I've needed it to do.

Thank you for posting this video. I've made many trips from Kansas City to Moab with an F250 diesel, slide-in camper, towing a trailer and Jeep. I'm intimately familiar with both routes you took through Colorado. My overall mpg for this trip is 11 mpg. The difference in the cost of diesel compared to your experience with gasoline is nil. For myself, I cannot justify the added cost of the diesel engine when the performance of the Godzilla across the Rocky Mountains is acceptable. An yes, I always get better mileage in the mountains than the plains.

Thanks for sharing your experiences and thoughts! We live in Colorado so we know the roads well!

Good job laying out the numbers. I run 2004 Silverado 2500hd 8.1(496ci) allison 5 speed 4x4 crew cab long bed. Tow 35ft fifth wheel. Dry weight 10,200. Combined milage for my last trip 1400 miles was 7.5 mpg.. All calculated by hand as my truck doesn't have trip computer. Thanks BRFO

Thanks for the great video. Today I got a call from my Dodge Dealer about my 2010 Dodge 3500 dually 4x4 Cummins 6.7 with 126k miles on it that needs a new turbo and I expect a $6,000 bill. I’ve always been a Ford guy and loved my F250 v10. Today I have become a born again Ford Gasoline guy.

Very good video with great information on the 7.3. It’s a great truck and I’m glad to hear it did good with the engine and trans braking. I’m used to diesel towing, but this gives us something to think about. Thanks for sharing.

Excellent video and thank you for sharing. We have a 22 F350 with the 7.3 engine and 430 gears. So far here in North Carolina we’re averaging about 8 to 8 1/2 at 65 mph with a grand design reflection, 337RLS fifth wheel. The weight is about 11,000 empty and max weight is 14,000 and we are somewhere in between currently. So far the truck has about 5500 miles on it and he’s doing pretty doggone good. We are really impressed with how well it handles with and without the trailer. I should also mention that we put a goosebox MK3 in place of the standard pin box and the b&w goose ball hitch and pucks to hook up the trailer to the trucks 0EM fifth wheel prep package that came from the factory. The truck unloaded gets about 14 1/2 miles per gallon at 70 to 75 mph per hour which is not too bad for having 430 gears

I ordered a 22 7.3L F-350 SRW with the 3.73 In December of 21. I took delivery at the end of August of 22, and have put 5K on it. Unfortunately I have only towed once with it because it was the end of the camping season, and looking for spring to start again so we can tow more with it. The truck is absolutely great. Around town I consistently get 13mpg. When on the highway I was getting 17. Towing the 1 time I was averaging the same as our F-150 with our 8K 30' TT at 10mpg.

Ordered my 7.3 tremor the other day. Can’t wait.

This was a great video, i'm in the scope of looking for a larger truck with a gas engine. I currently have a 2020 DC Tundra and i'm towing a 27' TT and getting 6.5MPG. So this video was extremely helpful in making a decision. Thanks for making this video.

Good honest review I'm very pleased with my F250 7.3 with 4:30 gears. I tow smaller weights than you, hay bales and tractors about 10,000 to 11,000 lbs so not enough to benefit from a diesel but more than I was comfortable with from my F150. Like you I tow in 8th gear but this is on back roads not highway. Will have to check out your other videos.

I live outside of Denver and Drive to Texas often, sometimes Florida via Tennessee. I get great mpg in the diesel or the 5.0 coyote for most of the trip, until I get back to Kansas heading home….then it starts dropping quickly,I have had times that headwind was so bad when towing I had to pull over and fill up about every 200 miles. Thanks for the video, I have been considering trading the diesel in for the 7.3 Gaszilla

Thanks for the well detailed trip mileage, the course taken, total package weight, wind, elevation and grades. This adds a lot to understanding the fuel mileage. I have a F-350 SRW, Diesel, 4wd, crew cab The payload penalty of a Diesel, along with its substantially higher maintenance and repair costs lead me to consider trading it for the 7.3 gas engine. You mentioned how mileage suffered due to the Kansas headwinds. This is one topic I've studied in detail on my truck. With a negligible load, on a flat grade, and no trailer, I have recorded the following MPG (below). The bottom line is winds and high cruising speeds are VERY significant fuel mileage detractors. 60 mph = 20.0 mpg (went over 900 miles on one tank of gas (48 gallon tank on the long bed trucks) 65 mph = 18.3 to 18.8 mpg 70 mph = just under 18 mpg 85 mph = 13.3 mpg (on Interstate 80, outside Salt Lake City, speed limit 80 mph) 11.0 mpg (Speed was 65 mph BUT there was a ~40 mph headwind. So, the wind load was comparable to ~100+ MPH When I saw the mileage dropped to 11.0 mpg, I thought something was wrong. But as soon as my heading changed and I got out of the wind, the mileage returned to 18+ mpg. These trucks are as aerodynamic as a large wall. Pulling a tall fifth wheel is even worse. I bet that if you slowed from the 70 mph you mentioned to 65 or even a leisurely 60 mph, your mpg would jump up quite noticeably

Excellent video! We have a 2021 Class A motor home with the 7.3 Godzilla gas motor and 6spd transmission. On our last trip we averaged 7.3 mpg, weighed about 22k lbs, tow a small car and clocked about 6900 mi. We went from south Mississippi to Montana, over to Philadelphia and then back to Mississippi. The engine brake worked really well in the mountains. It was loud but worked well.

We tow a 30 foot Grand Design fifth wheel with a RAM 2500, 6.4 Hemi, 6 speed transmission and a 3.73 rear end and get similar numbers. Around here in Texas I get 8.5 but when when get to the mountains or open plains I would say we average about the same as y'all did.

I love my 2022 F350 SRW FX4 7.3 Long Bed truck. That motor is truly well thought out design. I am VERY pleased with my purchase decision. I have enough money to buy my truck the way I want and I chose to go gas engine since I mostly use the truck as a daily driver not under load and I don’t haul 20,000 pounds ever.

I've driven a range of different vehicles in the rockies and mpg is always the best. I put it down to reduced drag in that thin air.

Fantastic fuel milage for weight and size your rig!

Great video, will definitely consider your experiences with next purchase, was concerned buy a 10 speed, maybe best option.

My next door neighbor this winter, bought a new to him huge 3 axle toy hauler, 14000 pounds. He got the gasser and it tows that trailer OK.

We have a '22 F350 with the 7.3 and 4.30 axle, and we are towing a GD Reflection 311BHS which is a little bit bigger and heavier then yours (11k Dry/14k GVWR). We live in NH and have been around NH/S. ME/NY and out to KY with this setup. Cruising on the highway (cruise control for the most part) at 65MPH I can typically get a good solid 7.5 MPG hand calculated. If I go up to 70 MPH I'll drop to about 7 MPG. This past weekend we went to a campground about 75 miles from home and took "scenic" 2 lane state highways with the highest speed limit at 55MPH and got 8MPG on that tank. I typically do not lock out gears, although on our last trip out to NY I tried locking out 10th and the truck seems a little smoother in picking gears on the hills but not significantly better. I say that because you mention locking out 9th and 10th on your truck, and I'm thinking that is effecting your MPG's more then you think... you might just be able to break 8MPG with your setup if you let the truck use all it's gears.

Thanks for the info. This gives me a good benchmark for improving my situation. I’ve made 3 similar trips out west from NE Arkansas heading to Montana but returning very similar route through Utah, Colorado etc. I’m much lighter though and using an F-150 5.0 liter towing around 6000 lbs averaging 10.5 to 11 mpg. My fuel economy is more important than time because I’m not on a schedule. However my truck has really struggled out west with those stinking headwinds and hills, sometimes causing me to downshift all the way to 2nd gear with rpm’s shooting up to 5500. I’m usually exhausted and ready to trade by the time I get there! Very much considering more power in the form of the Zilla 7.3 in a F-250. I think with my speeds and lighter towing I can get comparable mpg and no more second gear!

I just subscribed. I have the same truck but a 2021. I love the truck but just wish it had just a little larger tank. Yes the engine brake does work very well.

Glad to find a great channel. I have a much smaller setup. 2020 150/w 2.7. Outfit weights just under 9000. I have been impressed with the ability of the truck. 14.9 MPG, plenty of power. May try another 350 if the prices drop. Appreciate the great video.

My 22 f350 with 7.3 I get 1.5 mpg better by putting it in manual shifting and using the cruise. Mine likes to go from 8th to 6th in auto mode. 90% of the time I don't need to downshift past 7th. Thinking about a tuner to make it hold gears a little better. I sure do love my 7.3 tho.

BRFO thx for an informative video of your travels with the Godzilla Ford PU and camper. I have been following this engine since Ford 1st announced it as like your previous rig mine is 1t DRW D'Max and gets about 9-10 mpg with 40' 18k# tripple axle TH with total of 26k#. The cost of fuel and health issues have kept us off the road as in Komiefornia Gov Nauseum has current taxed diesel to $5:50gal . We're looking to relocate to AZ and might have to downsize to similar rig as you but still have MCs to haul so might end up with bumper pull and gasser PU for TV and flat floor plan for wife's knees. I'm not a Ford fan after owning a few in over 55 yrs of driving but am disappointed in GM's Chinese collusion and their lack of support to those of us who bought their pricey PUs with Bosch's time bomb CP4.2 HPFP. I might end up with a Blue Oval in my driveway yet unless Ram brings back a big hemi with low-end torque and a super charger with Aisin trans. Happy Camping and stay healthy. Ps subbed.

Good review of the motor and real world tow testing.I have a 2021 E450 class C motorhome that weighs 13,000# with water and fuel and tow behind another 7000# (Jeep on a trailer). I was stoked that it has the new 7.3L gasser Godzilla motor but was kinda bummed it still got the 6 speed tranny. I live in Utah and travel all over for vacations and as you experienced, it’s got some big hills to climb. After watching your vid, I’m kinda glad I it got the 6 speed but still wonder if I could get better with the 10 speed. The one thing I don’t know is my gear ratio(no vehicle build sheet when buying a motorhome) but I do run at 2000 rpm at 65 mph. I average 7.7 mpg and my best was 10.4 mpg and worst was with the heaviest head wind I ever experienced. I don’t worry about locking out any gears with the 6 speed but it usually only kicks down to 5th and rarely to 4th gear. I know one thing for sure, my next 3/4 truck will be with this motor, super pleased with it and it’s low end grunt as I won’t run it over 3500 rpms as it don’t need it going up those bill climbs. Just curious, what’s your fuel mileage as a drive empty around town truck.

My buddy has one, he pulls a toy hauler from Texas to Utah and Nevada, he had his tuned with HP tuners, which are licensed by Ford to change the computer programing, not a chip bypass, and he is now getting 10.3 MPG. When tuned for the work the truck is doing and the fuel you intend to run, tuning optimizes the engine for an efficient clean burn. Remember ALL vehicles are set to match California climate NOT the climate you are in or elevation. This makes tuning a must for your intended use and area. I had my 5.0 flex fuel tuned for my elevation, Corpus Christi, sea level and hot climate and my fuel mileage improved and so did my performance. Well worth the 300 dollars for the tune.

Very interesting. I'm considering ordering a SRW F250 7.3 3.73 gear to haul a slide-in camper. I very rarely tow so that's not as important to me as the payload, but based on your numbers I think could get 12+ mpg with just me and a light popup camper. Honestly, I'd rather get a F150 3.5 ecoboost for less money and better mileage, but it would have to be a base XL to get that payload I need and prefer the XLT. That said, the F250 XLT isn't too bad if you limit the options.

Great, informative review! Thanks! Curious as to what the truck gets without a load, in eco-mode on the highway?

Watch you rollers and cam at 45,000 mi...seen alot of delaminating....garbage parts internally no matter your maintaining track record. Also we went to Moab and green river , utah.. loved it we drove from Cleveland to Moab 1600 mi each way and I have a 17 ft travel trailer about 3 tons and with a 1500 silverado we ran about 10 mpg in the rockies...

I'm glad that Ford didn't try to build an HP/Torque monster and sacrifice reliability. I'm also looking at an F-350 with the 7.3. My current trailer is more than towable weight/payload for my F-150, but at Ball > Bumper of 31.5' that is a lot of trailer to put out for wind to react on. A larger vehicle, with eventual plans to step up to a 5th wheel, make this a good investment.

Just did a trip out to Utah from Miramichi New Brunswick, Canada. 2022 XLT F350 6.7L crew cab short box single axel 3.55 rear end. Towing a 2012 Jayco 265RLS 5th wheel (most with water in the tank). Total trip was about 13 000 km computer said I averaged overall 17.1 L/100 KM (13.7 MPG).

I also have the 2022 7.3L f250. I pull 10K trailer all the time. After playing with all the gas options on E88, 87,89,and 91…I have best results mpg on 89. Plus seen a big difference on fuel per mpg. I run average 60 mph and I get 9.2 mpg up and down interstate 95 which is pretty flat. Just by running 70 moves it down to 7.6 mpg. The only issue with these motors is the low oil pressure at idle. So people that sleep in their cars with it running at rest stops is where all the damage is done. They are known to destroy lifters with long idle times. Other than that, they are good engines.

Time for the transfer flow 58 gallon tank install

Very similar fuel consumption with our 22 F350 crew cab long bed 4x4 4.30... Our trailer is about 9500 and like most TT's it's like pulling a parachute.

I have the exact same f250

My 2021 E350 cutaway van with the 7.3 Godzilla motor has the 4.56 gears 😱

Yep. When towing travel trailer cross country with 7.3l Godzilla getting average 7 mpg depending on wind/elevation change. It’s not great. For reference, I was towing the same travel trailer with a first gen ecoboost f150 on multiple cross country trips towing, and averaged 9.5 mpg. One time with a tailwind we covered a couple hundred miles getting 13 mpg. I was cracking up

Great video, much respect for the long trip you did and the Godzilla engine. We live about 5 hours south of you on the south side of Atlanta. We have a trip planned this August towing our Grand Design 2800BH with our 2022 Chevy 2500hd gasser to Naples, ME. I can't wait to do it and will be doing the hand calculation as you did for fuel mileage. Right now after just a few times towing our camper we get about 8 to 10 depending on hills of course. So I can't wait to see how our gasser does on an approx 3400 mile round trip up there. I know a totally different truck but still a HD gasser. Much respect and a great video. Subscribed!!

Great review.... I'm in the market for a 22 platinum tremor 7.3... then supercharge it when the warranty runs out... Talk to many many Ford dealers here in Colorado with 6.7 powerstroke waiting for parts for 4 to 6 months🤯 no thanks

well I love my 2021 7.3 f250 but when the power steering pump went out at 60,273 miles and has been in shop for 2 weeks and counting because can't get one

Just traded in my 2017 f-250 with the 6.7 diesel for a 2023 f-250 with the godzilla in it with 373 gears hoping that i love it supposed to be in right around labor day we pull a 2023 335cg keystone outback outback about 10,000 lbs crossing my fingers i made the right decision,, thanks for the info

Looking forward to my new used 21 model with 7.3 coming in. Sold my 17 model f350 dually to get this one. I was over daily driving a dually and paying high diesel prices. I have a 44ft toy hauler that's around 16,000 max loaded. Best I got with the dually was around 8.5-9mpg. I figure the 7.3 should be around 7.5-8mpg hopefully pulling it

this video was great. i own a 97 7.3 PSD and cannot stand how poorly it goes even with all my modifications-i regularly pull 10k across the rockies from one end of colorado to another. i also regularly use a 2020 tundra for the same purpose and surprisingly they perform about the same (big plus to the tundra! a modern half ton compared to an older 3/4!) that being said, i was gonna buy a 6.2 ford. however, the 6.2 is pretty comparable power wise to the 5.7 iforce and i just haven’t been super impressed with it over the rockies. i plan on eventually getting a gooseneck race trailer and it struggled pulling i70 at 6.2mpg with ONE car, so i decided to hold off on buying a truck and wait til i can just buy a 7.3. this video confirmed my choices! not only was it comparing a tundra, but it also included my stomping grounds and the roads i regularly drive! ps, tundra has 4.30s:)

Great video, thank you very good information. Is this truck a long bed?

2021 coachman pursuit 35 ft gas 7.3 class a towing 2019 Colorado avg 68 /70 mph getting 7.5 avg mpg if i ran at 65/68 prob get 8.0/8.5 mpg.

Just wondering if you F350 has the same settings as mine 15 F350 where you can change the mileage calculation. You can select either standard or towing. It might actually even be closer than the .2 miles/gallon. Also another thing to think of is how many miles were on your pickup before your cross country trip? You might actually get better mileage now because your pickup will have more miles and past the "break-in" period.

The only thing that concerns me about the 73 is that I've been hearing and scene and other videos it the Cam shaft lifters and the Cam shelves are delaminating after about 40 to 50000 miles.

Thank you for this detailed information. I have a similar F-350 7.3 with the 4.3 gearing towing a travel trailer and am about to step up to a similar sized 5th wheel. It looks like you have a short bed-can you tell me what hitch you are using with that 5th wheel and how you like it?

Not bad for a gigantic v-8

Excellent Video I just bought a 2022 Xlt f250 4wd crewcab traded in my 2013 f450 true cab chassis because the cp4 pump failed and I don't trust bosh and the worthlessness of the 6.7 love the 7.3 been watching it sence 2020 all I use the truck for is to tow my 26ft dune sport toyhauler witch fully loaded for dry camping is I'm thinking 13,500 but haven't scaled it will do soon,I dis tow it up our closest big hill getting out of town witch is called sunset point with 46 miles on truck 😊 Truck blew my mind probably shouldn't of pushed it as hard but I needed to see what it would do steepest parts 7° up 70mph ran 4th/5th with tons more power Coming down hill other side dis better then my diesel in braking in tow/haul AMAZING love this 7.3 godzilla and yes I have the 3:55 gears and it ranged from 6.0-5.4 miles to gallon but here in AZ all good Great videos I subscribed and following 👍👍👍

Good video but you need to start using 9 and 10th gear when you can and your mpg will improve to the 8.5 to 10 range. I have the same truck as you 2021 year. I have 135k on it as of right. I pull a 32 ft gooseneck trailer and 80% of the miles are loaded as I use it as a hotshot truck. Average loaded trailer weight is 12 to 17k pounds. Trany oil was changed by me at 120 k and although dark there was very little on the magnet and I could see no metal flakes. Was very impressed by that. Anything above 6th gear is in the overdrive range. I do however turn tow haul off Going down hills and shift id down my self. Only time I'll limit how high it goes is if I'm hitting a big head wind or it the rockies and I'll down shift it myself in those cases as well. Good luck your going to enjoy the truck.

you can use 9 and 10 now days. the PCM will drop back when needed based on load and save you fuel when lower gears isnt needed. 7.3 makes 400lb-ft at only 1500 RPM

I might have missed it (new to the channel) - why not go PowerStroke for all of the towing? Less complexity and acquisition cost of the 7.3?

The big question is when you went over wolf creek pass did you sing the song? Lol

Love this video, Thanks. You said this truck has a high payload, what's your GVWR? Are the upper gears locked out in Tow/Haul mode? I'm looking to get one of these.

Transmission temperatures while pulling up and while engine brake

I have 2022 7.3 with 4.30 rear axle it’s a monster didn’t buy for fuel mileage

My 7.3 is the same. I don’t lock it out I just let the tow haul mod do it’s job I live in salt lick , ky I tow my tractor and my cattle it’s a great truck. I really don’t care about fuel mileage to much were it’s always loaded. It seems to be the same even when I tow my gooseneck

I have 17 350 6.7 flat ground towing 10.2 mpg mountains or headwinds 7 to 9 mpg pulling 35 foot 5th wheel so tre savings on fuel alone is huge let alone the upcharge for diesle and def and maintenence sounds to me youve got it going on my trailer is 13000empty 14500 loaded. ill be looking at your ttuck in the future'

Great video. We are FT with a 43ft 5th wheel. I loved the 7.3 , but no way was I towing FT with a Gas motor. We also went from FL to UTAH and I did the fuel mileage by hand. Our computer was almost spot on every time. It was off about .1 in the mountains. With the 6.7 we got 10.7 heading west and 11.5 coming east. Our 5th wheel is just shy of 18k lbs loaded. I attribute that mostly to headwinds going west. I drove 65 with cruise control 95% of the time. My only issue with the Gas engine is fueling up on the fly. Seems to me you would have to plan your stops. Also, I carry 60 gallons of fuel in the bed, so a total of 148 gallons. I am pretty sure carrying aux fuel with a gasser is pretty difficult. I will say the thing felt great when I drove it. Just some background..our first TT was towed with an EXcursion with the 6.8 v10. I loved that engine and I could tell the 7.3 was by far superior. I will be interested to see how it holds up in the long term.

When you mentioned engine braking, is that just downshifting? I know the diesel has an engine brake. I didn't think the gas has anything like it? Thanks for the information.

Great video. I live near I 70 just west of Denver and took the same truck out last week with my 11,000 5th wheel. One difference is I do have the 4.? rear end. I found even with manually shifting to 3rd gear going downhill the truck was wanting to still speed up past 55 mph. What gear were you down shifting to when going on the speed hills in the Rockies?

I assume you ran 86/87 octane fuel for this run. I saw somewhere that ford says there is an actual benefit to higher octane when towing with the 7.3

Holly crap that is some crappy milage in my opinion. Our ram with the 6.7 Cummings under a 20,000 load gets on average 14 mpg. We run a hotshot company and put about 100,000 miles a year on our trucks. Out Cummings spend about 1/2 the time in the shop as our ford's

25 mph headwind means you were running with teh equivalent load of towing at 95 MPH if you were doing 70. yikes. glad to hear it didn't loose speed though!

I have a 250 with the 3.73 gears

I had no idea that The 7.3 had an engine brake! 😮

I have a 2020 F350 7.3 with the 6.7ft bed. My biggest complaint is the size of the gas tank, it’s smaller than my old F150 5.0 :(. I’ve searched for a larger tank but can only find larger for the 8ft bed.

Getting a new F250 with 7.3. Did you have any trouble fueling up on the trip? Getting into gas stations.

What's the take on the cam and roller issues they're having at low mileage?

If fuel cost is important, just slow down. I’m getting at least 10 mpg going west and as high as 11.8 mpg going east. F150, 5.0 liter, 10 speed, 3.55 axle, towing a 8,000 to 9,000 lb trailer from MN to AZ at 58 to 60 mph. I lock out 7-8-9-10, and run 6th gear on the flats at 2700 rpm, and 5th gear in the hills at around 3200 rpm. Non towing is 22 mpg highway.

Why do you lock out the upper gears when towing? I’ve not heard that before.

It may be there but I did not hear it. What speeds were you running?

Awesome video, and Why are you worried about towing in ninth or 10th overdrive’s?

Don't feel bad 03f150 355rear 5.4 2v, 6% grade most of the way 8500lbs extra tall trailer... 5.8 mgp Came here for the 7.3 gas review. Awesome 👌

Can you elaborate in a detailed way as to how the truck actually engages the braking when going down hill? I know how it works on a diesel, not sure on a gasser. Thanks

I just bought a f250 7.3 gas. And wonder how do you turn on or use the engine brake. Thanks

I was thinking about getting a dully for the extra tires in case of a blow out. Am I overthinking it ?

7.3 Godzilla is notorious for lifter and cam failure, starting at 35,000 to 49,0000 miles. It seems the lamination eats of the lifters and cam. Watched it on YT
