We went back to a 32.5' travel trailer from a 32' 5th wheel. I have no regrets. The truck actually rides better with the TT. No chucking on concrete highways. No clunking starts and stops. We have no sway as we have a simple loading rule. We can load anything we can carry as long as it's in front of the axles. We towed it the first year without sway control. No sway but a little push pull when trucks passed if there was a cross wind. Earlier this year I bought a barely used Equalizer 4 point 10k off of eBay. No more wiggle from passing trucks. The TT is easier to back into a campsite as well with it's leverage point making it more reactive to the TV.
One of our 5th wheels, a rear kitchen, swayed quite a bit. Couldn't feel it in the truck but I could see it in the mirrors. Cured me of rear kitchen floorplans.
