We have a 30' travel trailer I pull behind the F-250 whenever I can squeeze some time away from people's yards. The hitch weight is around 800 lbs.. I have a Reese 1000/1200 lb. weight distribution hitch with dual-cam sway control bars to connect the two. I can't for the life of me figure out how to level the truck with this hitch. It was set by the dealer for my '01 F-250 but now I have an '05. The rear bumper is 30" from the ground alone but only 28" from the ground with the TT. The TT sits just as level as can be but the truck still sags. Two inches isn't drastic but I can sure see the difference. I've moved the adjustable ball mount bolts both up and down. The chains are only four links long when tightened and I don't have room to shorten that anymore. Am I missing something? Is there anything else I can do. This truck also has the "camper package" which gives it extra support in back so there really shouldn't be any sag at all with a 1200 lb. hitch. Thanks ya'll.
