Remove the tailgate, tonneau cover, side rails and drop in bed liner from the truck. This additional equipment will not allow for proper installation of the truck camper. Lay down rubber mats in the bed of the truck to prevent damage to the slide-in camper.
Jack up the slide-in camper using the jack stands. Raising the slide-in camper to the proper height will require four people working in unison. Operate the manual levers for raising the slide-in camper or use the automatic hydraulic leveling system that was installed through the manufacturer. Make sure that each person is operating the lifting system at the same time and lifting the camper using equal increments. Lifting one corner higher than another can cause the camper to topple over and result in severe damage and injury.
Position a team member at each corner of the camper. Back the truck up slowly in a controlled manner making sure to align the truck with precision. Let the team guide you. Continue backing the truck until it is completely under the camper, you have the proper clearance for the cab, and the space on either side of the bed is the same. This process may take several tries.
Begin lowering the camper. Start at the rear of the camper and lower the jacks in small increments. Lower the front of the camper in the same manner. Work back and forth lowering the camper until it is safely in the bed of the truck. Never lower the camper more than three inches at a time.
Attach the slide-in camper to the anchors on your truck. Your truck should have an anchor system in-place manufactured for your truck and camper combination. Use the hardware provided and install the anchors at the front and rear of the bed using the manufacturer's instructions.
Inspect the system to make sure you did not overlook any necessary hardware. Remove the jack stands and store them in a safe place. Test drive the truck slowly and inspect it for installation problems.
