I have a 2008 CM with a TRUXX 3in lift and level kit on it (3" lift in the front 1" lift on the rear). I have firestone airbags for the suspension and a pullrite 12k superglide hitch. I will be pulling a 2010 Keystone Xlite 27sab 5th wheel. I am picking this trailer up and I want to be sure I don't have any issues. Will I have enough clearance between the truck box and the bottom of the trailer? Can the king pin on the trailer be adjusted down easily to give me more clearance if possible?
