Did not watch the entire video or rewatch it - found it very disturbing. My impression was there was not a lot of braking going on. There were no skid marks on the pavement and not much for marks on the grass.

Perhaps the driver was trying to drive out of a flat tire. They tell you to add accelerator initially when a front tire goes flat. Perhaps they had a flat tire and the driver dozed off.

Obviously speed was a factor in this accident as determined by the amount of destruction to the MH. Would 10 or 20 mph made a difference?

20+ tons moving at 20mph faster is lot of kenetic energy.

a 43,000# MH moving 20mph faster adds 779414 joules of energy

or the energy required to lift 779414 apples 1 meter

10 or 20 less may have done less damage. This looks like it would have been deadly at any speed more than about 30. Even then there would have been substantial damage and injuries.

First, I haven't watched any of these video's...

But, not to sound facetious, but did anyone watch 'Breaking Bad' when they crushed that Bounder? They poked a pair of forks thru the side, lifted it up a bit, and that whole motorhome was reduced to toothpicks within a few seconds.

I would think if you stood most any motorhome on end with the engine in the air and tipped it over onto it's back it totally destroy the thing. It won't take many mph to do a LOT of damage...

Personally, I'm surprised RV's stay put together just driving the things. Last week I found a part of a rug in our kitchen trapped under the wall that surrounds the refrigerator. The ONLY way it could've got there is while the body was twisting and the rug was sliding, most likely going thru a gutter. The wall had to have lifted nearly 1/4" off the floor. We couldn't move the wall by ourselves to pull the rug out, I tore it trying, the piece left behind is still trapped.

Drop it high enough off the ground to impact at 20 mph - better yet, let it land on a corner, which would be much more realistic to a real life impact. Consumer Reports has for years maintained offset crash test are much more severe than a direct hit.
If you want to see some RVs not hold up very well to minor impact, and also watch a fun video, watch this one. It really didn't take much for these to come apart.
