Measure the box of the camper to be sure it'll fit through the tailgate. The newer pickups have narrower tailgate openings than older models. Had a friend a few years ago that bought a camper made in the late 1990s & when he went to get it with his new pickup, it didn't fit.
Also, try hard to keep the center of gravity in front of the back axle. It'll handle a lot better. 1500 pounds shouldn't be a problem.
