Ok so I just recently upgraded camper and truck. 02 Chevy 2500HD and an 04 Terry 32' travel trailer. We made some local trips to see how it would go. Had no problems. Replaced the tires on the truck and hooked up and drug it from Middletown PA to Cape May New Jersey. It felt like terrible sway. Only difference is tires and to be safe I put on the sway controller that came with the camper. I pull at 55 to 60 mph. Anyone ever install a sway controller and made it feel like sway. It didn't look like it was swaying in the side mirrors, but I definitely had a grip on the wheel.
