I just picked up a 2010 Jayco 32 BHDS with an empty weight of 7765, gross 9750, dry hitch weight 1005. I tow it with a 2009 GMC 2500HD 6.0L Gas Crew Cab 6'6" bed, fully trailer equipped. Everyone from the dealers (GM and RV) and friends who RV say I have enough truck for this trailer. However I'm concerned about how much I can feel the truck being pulled around by the trailer, and that the transmission shifts alot and I get high RPM at highway speeds. This truck really seems to be working on slight uphills. Is this all my paranoia and inexperience with towing, or should I be concerned? What can I do to make this better? I have a Reese hitch with WD and sway. With the WD hitch, the leafs aren't down on the bottom springs. The truck seems to be loaded correctly. I have not put on any cargo yet.
