A slide-in camper is a recreational vehicle that rests on the bed of the truck, turning the vehicle into a camper. Some models extend above and on top of the cab of the truck for additional space. Special tie-downs hold the camper onto the truck.
Slide-in campers offer versatility because they can go wherever the truck goes. The camper doesn't affect the maneuverability of the truck as much as a pull-behind RV.
Slide-in campers come in both hard-side and pop-up models. Hard-side models remain in the same shape and position. Pop-up models lower for travel and raise up while camping. Some truck campers have optional slide-out sections to create more space.
