Apparatus for supporting and lifting a wheelless, vehicle-mounted camper cabin includes built-in jacks for safely, quickly and easily loading and unloading the camper cabin with respect to a transporting vehicle. The apparatus can be attached to the camper cabin and suspended therefrom when the camper cabin is mounted on a vehicle, and the apparatus can be used to secure the camper cabin on the transporting vehicle, while eliminating the need for tie-down chains, turnbuckles or other inconvenient means of securing the camper cabin to the transporting vehicle. The apparatus can include wheels for enabling the camper cabin to be moved about when the cabin has been removed from the vehicle and supported by the apparatus. The apparatus is also very stable to permit safe occupancy of the camper cabin when the cabin has been off-loaded from the vehicle and supported by the apparatus.
