I have a 2006 dodge with a 2" front leveling lift. I'm wondering if you can even get the camper high enough with the jacks to make it into the lifted bed.
The primary limitation is with the tires and wheels. Make sure your tires are rated to handle the axle weight. My axle weighs 7200 pounds loaded on the rear. Nitto Terra Grappler tires are rated at 3750 pounds each and just barely make that requirement. Also, make sure your wheels are rated high enough to handle that weight as well. I had Hummer H2 forged aluminum rims and they were fine. I eventually went to Rickson 19.5" wheels and Toyo tires rated at over 5000 pounds each just to be comfortable and not worry I've over loaded the tires/wheels.
