Launching A Boat w/ A Truck Camper

Picked up an older C-951 a few weeks back that has undergone a complete top to bottom restoration which I will share when I have photos. Meanwhile I am hoping to go out soon for my shakedown trip and am thinking on taking my 21' Thompson boat along as well. Does anyone know if I can launch and retrieve my boat with the camper still attached to my truck bed? My truck is a Ram 2500 with an 8' bed and it does have 4 wheel drive.

Thanks.....Joe
