How Does the OVS Expedition Truck Cap Install?
The OVS Expedition Truck Cap uses a no-drill clamping system for simple installation without permanently modifying the truck bed. The process involves positioning the cap, securing the clamps, checking the seals and alignment, and connecting the third brake light.
Installation Steps
Step 1: Position the Cap on the Truck Bed
Place the assembled truck cap onto the bed rails and position it correctly for the vehicle.
Step 2: Align the Cap Using the Fitment Points
Align the cap with the truck bed to ensure proper fitment and even positioning.
Step 3: Secure the No-Drill Clamps
Attach and tighten the included clamps to secure the cap to the bed rails without drilling.
Step 4: Check Seals, Doors, and Alignment
Inspect the perimeter seals and confirm that the doors open, close, and latch properly. Check that the cap remains evenly aligned with the truck bed.
Step 5: Verify Brake Light and Hardware
Connect and test the third brake light, then check all mounting hardware and clamps to ensure everything is securely installed.
