Supercup explained perfectly. I am new to the RV world and have the 2020 trail boss 5.3 10 speed. First time I drove the new trailer (23' Stryker toyhauler 6,400 ibs dry)I was definitely white knuckling it. Winds were a little higher (18mph) and it takes some getting use to. Once I relaxed things got a lot easier. I didnt notice the squat too bad. A couple things I did notice; the shocks will need to be upgraded at some point because they are soft you spend a lot of time bouncing or rocking up and down. I also have a weight distribution hitch and anti sway bars. As supercup said there is still some side to side movements with wind and larger trucks passing you with the flow of traffic. Some of that movement could be the tires but a large part of it is that big sail you now have on the back of a fairly light truck for what we are doing. I am still running stock but would like to, at the very least, upgrade the suspension at some point. Hope this helps.
