My two cents, the larger & longer the tow rig, the better the ride, handling, and steering will be (primarily tongue-pull trailers that is).
The shorter and lighter weight the vehicle is, it will be more prone to the trailer "driving" the truck instead of the other way around.
I don't know how many times I've seen a small vehicle rolled (or the evidence of the aftermath, skidmarks from L to R increasing in size) just over the crest of summit where it got the death sway going as soon as he
let off the gas on the downhill side.
I always see the guy who bought too small a vehicle, and then has to add overload springs, air bags, etc, etc just to make it function at all, and it still doesn't do the job adequately in towing capacity, power, breaking and overall safety.
After spending my entire life in RV's from tent trailers, campers, TT's, Minihomes, always bring enough tow-vehicle!
Whatever direction we're traveling, that is the way the wind is blowing from.
