We utilize a truck-specific installation kit in the bed of the pickup. Firstly, this ensures that the SpaceKap does not sit on the truck’s rails but rather the weight is transferred to the truck’s floor bed. Secondly, it safeguards the SpaceKap from moving left to right or front to back. Finally, the cap is secured to the truck rails on all four corners with a patented tie-down system, preventing it from lifting out of the truck. No bolting or drilling is required.
