How to Support a Truck Camper

Explore America's Campgrounds

Truck campers are usually supported by the truck hauling them. But if you are taking your camper off the truck to store it, you should use some additional supports instead of relying on only the camper jacks to support your camper. Also, if you like to take your camper off your truck while camping, placing supports beneath the bottom (or sub-floor) of the camper will help keep it stable as you move around inside. Always use supports in conjunction with your camper jacks. Don’t rely on supports alone to hold the weight of your camper.

Items you will need

  • 3 sawhorses

  • 3 pieces of plywood, 1 foot by 3 feet

  • Level

Step 1

Make sure the surface the truck camper will be supported on is flat. Also, check that the ground beneath the camper is solid and dry; cement or packed gravel is best. Avoid muddy spots, grass or soft forest floor.

Step 2

Use truck to back camper into the place you wish to leave it.

Step 3

Detach the camper tie downs from truck. Unplug the camper’s power plug and light plug from the truck.

Step 4

Use the camper jacks to raise your camper approximately 6 inches out of the truck bed. Raise the front jacks, then the back jacks, only a couple of inches at a time, to avoid uneven weight distribution. When the bed of the truck is clear of the camper bottom, drive the truck slowly, straight forward, out of the way of the camper.

Step 5

Slide the three sawhorses beneath the camper’s sub-floor. Position them width-wise, one across the rear of the camper bottom, one across the middle, and one across the front end.

Step 6

Slide one piece of plywood onto the top of each sawhorse, to help distribute the camper’s weight, and protect the bottom of the camper.

Step 7

Using the camper jacks, incrementally lower the camper down onto the three sawhorse supports. Lower the back jacks a couple of inches, then the front jacks a couple of inches. As the camper’s bottom approaches the plywood atop the sawhorses, watch carefully to make sure the plywood stays in place. Stop lowering the camper when the sub-floor is making firm contact with the supports. DO NOT lower the camper beyond this point. The four camper jacks should also be supporting the camper’s weight. Lowering the camper completely onto the sawhorses will damage the sub-floor, and potentially the tanks and components within. Use the level on the inside floor of the camper to ensure the camper is resting flat.


  • Do not get beneath a truck camper when using the camper jacks to raise or lower it.
  • Never raise the rear section of the camper higher than the front section. The front section weighs more, so pushing the rear section up too high could potentially topple the camper.
  • Don’t extend camper jacks while the camper is attached to the truck. Doing so could damage both the truck and the camper.


  • Collapsible metal sawhorses are easy to transport and store for truck camper support, and they’re generally sturdier than wooden ones.
  • Shim the feet of the sawhorses with small, flat pieces of wood if they are going to be resting on asphalt in hot weather.
