Any truck camper should fit? they are designed to fit between the wheel wells. If the truck camper is made for 8' bed or 6.5 foot bed they fit. You might have to take the tail gate off.
I been using one for a couple of years now and love it.
Some campers have stowage pockets "built out" the full width of the gate entrance, and some have a "step" which goes "down inside" the tops of the bed rails. If you look closely you can see that pop-up I was considering is just that way
"It won't fit." The guy selling it found this out (Ferd) and he said a guy looked at it with a 94 Dodge (first year for this) and it would not fit his. Won't fit my 97 either.
If it was as simple as the tailgate "back plate" I could either cheat and let that hang out the back, or maybe (depending) trim it off.
