Thanks for the comment! We are loving Edna, she takes some work to keep in good shape but it's a joy to keep her on the road!

I'm glad you like the video! I'm mostly a mechanic and builder when it comes to the coach, I hope to be a craftsman someday :-)

Thanks for the comment!

Very cool! There are a lot of these still on the road. Thanks for the comment!

Glad you liked it!

Glad you enjoyed it!

Thanks for the encouragement! It's been a lot of fun keeping her on the road and we expect to do more camping in the future.

Scarry! Before we had our carb rebuilt, she would die on the road some times and the vacuum pump would kick in and do it's job. It's bad enough not having power steering but at least you can stop.

@MrGMCMotorhome I love the GMC Motorhome community. So many good natured folks willing to help each other out with informative tips on some of the nuances of these feisty beasts. Suffice it to say...despite all the overwhelming work that needs to be done on em, they are awesome and worth the effort. 🇺🇸

Thanks for the comment! This is the first motorhome I have owned but I think it was really well designed and, other than some mechanical and safety things, I don't see much need to improve on the original design.

A C5 Z06 would be a fun way to get around when you have set up camp :)

It would be great if GM would do a modern version of the 70's classic. I'm not going to hold my breath though.

I think they should make these now ..they are perfect ..not too big not too small , and it's layout is really awesome, and the bathroom was pretty amazing for it's time it's still better than most even now. Upgrade the bathroom it would be so great .

And it even came with its own vaccuum ?

@@mariamaria2751 I agree. Why they were ever discontinued in the first place is beyond me. It's perfect in size. It's perfect in shape. They got it right the first time. The only mechanical upgrades I'd make would be to install a GM 6.5 litre Turbo Diesel engine and a compatible 5 spd. automatic gearbox, preferably one that allows manual downshifting. 🙂

I really like our motorhome and I think it's worth the maintenance, upgrades, and work. The reality is that it's a combination of a 50 year old collector vehicle and a 50 year old house. No matter how nice your example is, it will need work. You should go into ownership planning on spending time, technical knowhow, and/or money. This is not a cheap hobby. The good news is that parts are readily available and it's a pretty simple vehicle/house and every motorhome will need work. I have a neighbor with a brand new 30 foot camper and it has spent about 50% of it's time in the shop over the last year. Here is a video where I talk about how much we have spent and where the time/money has gone on our coach. kzfaq.info/get/bejne/r8ikeLOguqvZiZs.html

Thanks for the comment! The vacuum pump is from Summit Racing (www.summitracing.com/parts/sum-760152) I'm very happy with it.

Thanks for watching the videos, I hope you find them useful! I haven't seen any OEM air filter housings. You may be able to find a Toronto air filter housing at a junk yard, I bet there are also lots of aftermarket Quadra Jet air cleaner housing. You may try a facebook post in some of the GMC Motorhome groups to see what others have done.

Good catch! That was done by a previous owner so I don't know much about them.

No electronics at all on ours. I don't think OBD was coming before the mid 80's and OBDII wasn't required in the US until 1996.

The mileage depends on a few things. Cursing on mostly flat roads at 60 mph we can get up to about 10mpg. If we are running the generator much or going over mountains we get closer to 8 mpg. We have tracked all our fill-ups and miles for the last 2 years and we are averaging 8.7 mpg over 3,200 miles. Good luck on the possible purchase, we have really enjoyed Edna!

Thanks! I haven't driven our coach in the snow but I've been on many gravel or dirt roads and it does fine. Washboard roads are a bit rough on the old girl though.

Good question, the operators manual describes how the bunkbeds work but don't list a weight capacity. I have seen several people comment about having people weighing over 200lbs sleep up there so I think it must be at least 250lb but I don't know for sure.

Great question! We often will travel at about 60-65 on the highway and average about 8 mpg over the 1,700 miles we have driven so far.

I haven't got to new windshields on my "to-do" list yet. However, I think there is a company who still makes these still. There are windshield replacement clinics at rallies and I know someone who ordered new windshields and had them put in by a local body shop.

I have thought about both and will probably do them at some point. There is a reason most new cars have both, nice to have and improved safety.

@@MrGMCMotorhome yeah some new pick ups have the cam integrated into the 3rd light

This is where it would be cool if there was some sort of electronic tinting system. Sort of like what's in the newer welding helmets. Where you can turn it off so the windows are clear and adjust the tint towards darker as needed. Or even set it to automatic so when the sun is bright, they tint darker. When it's dull out, they lighten up.

I'll need to do some research before I do any window tinting. I'm considering a ceramic tint like this: www.3m.com/3M/en_US/p/d/b5005118130/ It doesn't have to be dark to reduce IR and UV radiation and provide some privacy.

You don't buy a GMC, you adopt her.

AND YOU HAVE 2?🤣🤣🤣

@@tdmallet yes...a 78 royalty and a 77 the king... thanks cw

There are a few people who have done diesel swaps, I haven't heard of an LS swap. The challenge is the front wheel drive setup and limited height available to fit under the floor. Most people stay with the stock engine because it does the job well and is reliable and easy to repair or rebuild when needed. It's common to add fuel injection when people want to modernize it a little.
