Be sure to check the back width of the camper. I believe the older Alaskan Campers have a very wide rear--they fit snugly into the back of older trucks, but not for many of the newer trucks with narrower tail gate openings. The Alaskan camper I had, a 1972 CO, had a butt-ectomy where the asymmetrical right side was trimmed inboard about 4 inches, and re-skinned, so that it would fit into a modern truck. It was done well, it took me about a year to realize the trim on that side was different that the left side, plus I saw photos of other campers with the larger width, and being asymmetric, in the back. I suspect many of these older (pre 1990's) campers had this done to them, as the truck's tailgate openings became narrower. At least, that was true for the Fords--the 1997 and earlier F250's were wider back there than the later models.
