New Truck, Soon new NL . How to prep the truck

Unless the 450 is built much different than the 250/350 you'll have to raise the camper to clear the cab. I used a sheet of 2" 8x4' styrofoam from Lowes. When loading be mindful of the camper centering in the tail gate opening and where your truck tail lights and the camper are - loaded all the way forward might cause them to touch.
