Abstract: A tent camper with a lateral slide-out room. The tent camper includes a camper main body that is pulled in a longitudinal direction by a towing vehicle. A roof, aligned above the camper main body, is movable between a lowered, storage position and a raised, camping position. A lateral slide-out room is coupled to the camper main body. The lateral slide-out room is movable in a lateral direction between a retracted, storage position and an extended, operational position, thereby allowing additional living space to be provided to persons within the tent camper.
