Hey, Shawn..
What kind of leveling kit did you put on your truck? I have a Keystone Raptor 299MP and when I hook the truck (2006 F250 FX4 CC SB) up to it the back end sags just a bit and I would like to level it out. I have a slider hitch and a B & M hitch also, so I think bags would probably be out (nowhere to mount them). I am thinking about supersprings - either the 3K or 5K ones. Is that what you've got??
