I picked up a pretty nice 11' camper last week. Its a little bigger than I really wanted, but was a great deal and looks almost brand new. I drive a '99 F-250 Super Duty with the 7.3 Powerstroke. It has airbags, factory overloads, and the Torque Lift frame mounted tie downs. The camper rides pretty good. No problems stopping, no excessive sway (in fact not really any that I could notice), truck doesn't squat too much with the airbags.
All that said, I intend to beef up my suspension a bit more before I start using the camper next spring. I plan on adding a sway bar and putting adjustable gas shocks all the way around. I might also install the compressor kit to inflate my airbags from the cab. Any other suggestions? I suppose that long term I should think about upgrading to an F-350, but that just isn't in the cards right now.
