I agree. Plus there is the issue of center of pressure that hardly no one talks about.

When I look at the picture of the 30Q above, I see that a gust of wind from the side will act on motorhome very close to rear wheels, and shouldn't affect front wheels proportionally. That concerns me more than weight because it can't be varied by how we load the RV.

Most motorhomes carry roughly 1/3 of weight up front and 2/3 on rear in order to match axle and tire load ratings, but if a crosswind gust hits it at the center of pressure which is far behind the center of gravity, then the motorhome may react much different than driver expects.

I'm not sure, but expect that the center of pressure from side wind forces should be close to center of gravity, and that's probably hard to build into motorhomes on present front-engine truck chassis. Just a guess on my part though.
