I am thinking of trading in my 248tb Coachmen Travel Trailer on a new fifth wheel and I have no idea what hitch to get for my truck. I have a 2001 Quad cad short bed 4x4. There are so many. I know I need one that slides aft and foreward so I don't destroy my cab when I'm backing up. The other question is I ordered my truck with the extra helper springs so I know there is a tsb on lowering the rear end but I really don't want the dealer to do that. They can't even put the exhaust manifold retention straps on in the right spots. Any help would be greatley appreciated. Peter Dunn
