Another take away from this experiment could be that having a 1/10 scale vehicle will severely limit your overall towing capability.

No matter how much science is being taught, these guys are still playing with toys for a living

I cringe daily as I see things not being set up to be towed well

Useful? Mate, absolute gold! Perhaps I didn't learn anything new but this is by far the best explanation I have seen. Should be mandatory to watch this video before you get a car license. Subscribed.

For everyone curious about why weight centered over the axle vs the same weight at the front and back doesn't yields different results - your trailer doesn't only pivot at the hitch/ tongue, its main pivot point is at the tires. So the weight at the nose and tail have a greater effect in relation to that center pivot point than weight centered over it. Think of the trailer like a lawn mower blade or any other rotating prop type thing. Once that starts swinging over the pivot point, it is harder to stop with tip/ end heavy distribution vs. centered distribution. Both orientations have the same effect in the vertical plane, equal pressure/ weight over the tires, but your other 2 three dimensional planes are affected differently.

This should be mandatory for drivers ed. So clear and the visual aid is perfect. Well done lads. Pints on me.

What's interesting about this is that in the US we have different requirements for towbar weights. While excessive nose weight is a sway adder, center weight is actually LESS favorable in terms of oscillation damping than a slight nose forward distribution, especially as it relates to speed. Note that in your test you have more than 31% tongue weight in the nose-heavy example. In the US we shoot for between 10% to 25% trailer weight on the drawbar or tongue. Studies have shown that as speeds rise this setup is inherently more stable than 3-5%. There is a study by delphi where they did rear world testing with 3% drawbar weight, 10% weight and -10%. They determined the point at which each one had oscillations that would decay, grow or stay neutral. With -10% the threshold was at 45 mph (72 kph). With 3% it was 65 mph (105 kph) and at 10% it was 100 mph (161 kph). Obviously, no one should tow that at 100 mph, but we tow at 80 mph all the time (legally). I tow a 1.6T trailer with my Prado (GX470) at 80 mph all the time in Utah. My tongue weight is about 12%. No problems whatsoever in any conditions. Obviously, common sense being the first priority when towing. This, coincidentally, is why US trucks have lower tow ratings than other vehicles because they assume a 10% tongue weight which cuts into their payload. Ram's Towing guide specifies this "it should fall between 10 to 25 percent of GTW". The tow standard here, SAEJ2807 calls for 10% for all official towing tests to determine trailer capacity. It would be really cool to see this play out on your demonstration table. I realize it's not a good suggestion necessarily to say you should run lower weight trailers but more tongue weight just like it would be a bad idea to suggest we can run heavier trailers with less tongue weight here. It's just an interesting data point.

That was accurate and easy to understand. I think everyone towing anything should see it. Great job

People really don’t have sense, this needs to be showed

You deserve a medal .

Great video. I have done a fair bit of hauling small machinery in a utility trailer for many years. Every move is a different adventure. One of the lessons learned is that I no longer travel behind other vehicles that are towing or hauling stuff. So many things can go wrong to them and I don't want to be on the receiving end of any of it.

Probably the single most concise info video on KZfaq. Impressive! Must see for all the new grey nomads infesting the outback. Have seen far too many caravan accidents recently.

The dynamic visuals on comparative weight distribution are excellent, should be shown to those lugging the genset, washing machine, additional fuel, 6 spare wheels and a moped off the rear of their van.

Unbelievably clear. Well done. You're really making the roads safer with this tutorial. Grateful for your attention to this. Thank you!

This was brilliant. It was great to see effects of changes v baseline on split screen. Clever scale model + treadmill setup as well.

That was absolutely excellent Robert. Yes, please more stuff like this. That rolling road model was the bees knees.

Best explanation of towing dynamics I’ve seen

Absolutely clear, your physical demo with models is the best way to demonstrate the cause and effect - hats off to you !!
