Hello, I'm pretty new to the 5th wheel towing and to this forum. Purchased a 2022 380FLR in the fall, have made two 2000 mile trips and numerous 300 mile trips. Towing with a 2020 GMC Denali 3500 DRW and B&W Companion hitch. Most of the time it tows like a dream, but on occasion will hit a bridge that really gets the rig to bouncing badly and also hit some stretches of I80 where the expansion joints about beat us to death. i have researched Firestone air bags, but see some threads that indicate those are more for leveling the ride than maybe controlling bouncing or smoothing the ride. Any suggestions?
