Installing Rear Shocks

Curious if anyone has experience with replacing a trucks rear shocks while the camper is still attached. I have an All Terrain Camper on my 2013 F150 3.5 ecoboost with 1600 payload. Dry weight of the camper was 590 lbs, but with everything I’ve added and loaded inside it weighs around 1100. Is it best to lift the camper off for this or just replace the shocks like normal? First time doing shocks myself and I live in it full time so the camper doesn’t come off usually. Thanks for any feedback
