We went from a 24' to a 35' three years ago. Although the newer camper was longer and heavier, the tow itself is actually equal or better to the smaller camper. I attribute that to the fact that we insisted on an Equalizer hitch for the longer camper. Prior to that, we were using a "cheap-o"
chain / friction anti sway with the older camper. I think some underestimate how important spending a few extra bucks on a good hitch can make.
Most campgrounds we visit accommodate the extra 11 feet so it's really no big deal.
BTW, we tow with a 2010 F150 crew cab with the 5.4 motor.
Good luck
