There are a couple options with mine. Spring loaded tiedowns need something extending from the truck frame or you can use 4 pins that have to align through 4 secure points. You can remove your campers factory brackets and fab up your own set using the same bolt pattern. Then you need to mount 4 secure points to your utility bed. Maybe someone will chime in with their pin system.
Keytag is correct about bed height. A quick reference is how much higher is the utility bed above the back window? That is how much you have to raise the bed. Obviously this is for a camper with slides right?
