Overland Truck Cap | Expedition-Ready Camper Shell
Our Overland truck cap transforms your pickup into a self-contained expedition platform built for serious adventure. We engineered this cap with reinforced construction, integrated mounting systems, and weatherproof seals that handle everything from desert crossings to mountain trails.
Every Overland cap features our dual-side access doors with three-point locking, a front sliding window for cab communication, and a textured powder coat finish that resists scratches and UV damage. The roofline supports up to 500 pounds of dynamic load for RTTs, solar panels, and gear carriers, while interior LED lighting and pre-wired power ports keep your systems running day and night.
Overland specifications & design
Construction & Materials Built for Remote Travel
We build the Overland cap around a fully welded aluminum extrusion frame that eliminates flex and twist on washboard roads and rock crawls. The outer panels use our proprietary composite material — a fiberglass-reinforced polymer that absorbs impact without cracking and won’t oxidize in salt or UV exposure.
Every seam receives a dual-bead adhesive plus mechanical fastening, creating a bond stronger than the surrounding material. The gasket system uses EPDM rubber compressed between the cap rail and bed rail, maintaining a watertight seal even when the truck frame flexes on uneven terrain. We apply a textured powder coat over a zinc-rich primer, giving you chip resistance that holds up to branch scrapes and gear loading.
Roof Rack Integration & Load Systems
Mounting Track System
The Overland cap ships with our proprietary aluminum track system pre-installed along both roof edges and the centerline. These tracks accept standard T-slot hardware, so you can mount crossbars, awning brackets, or custom fabrications without drilling through the cap. The tracks run the full length of the roof and include integrated drainage channels that route water away from mounting points.
Load Capacity & Distribution
We rate the roof at 500 pounds dynamic load when weight distributes across at least two crossbars. Most rooftop tents weigh 120-180 pounds, leaving capacity for gear bins, solar panels, and recovery equipment. The honeycomb core under the roof skin transfers vertical loads into the corner posts and down into the bed rail mounting points, keeping stress off the truck bed itself. For static loads — when the vehicle is parked and stabilized — the roof handles up to 800 pounds, accommodating two adults inside a rooftop tent.
Access Doors & Window Configurations
We equip every Overland cap with dual side doors that swing open 90 degrees and hold position with gas strut assists. Each door features a three-point rotary locking system — turn the exterior paddle handle and steel rods engage the top, middle, and bottom of the door frame. Slam latches on the interior let you secure the door from inside without needing the key.
The front wall includes a sliding window with an aluminum frame and tempered glass. The window locks in any position along its track, and a removable screen panel keeps insects out while maintaining airflow. We seal the window with compression bulbs that stay flexible in temperatures from -40°F to 140°F. The rear door frame accepts either a solid panel or our optional third door with a matching three-point lock, giving you walk-through access from the tailgate.

Common Questions About the Overland Truck Cap
The Overland cap supports up to 500 pounds of dynamic load (while driving) when distributed across at least two crossbars mounted in the roof track system. Most rooftop tents weigh between 120-180 pounds, leaving 320-380 pounds of capacity for additional gear, solar panels, and recovery equipment.
When the vehicle is parked and stabilized, the static load capacity increases to 800 pounds, which accommodates two adults sleeping in a rooftop tent plus gear stored on the roof. The honeycomb core roof structure distributes weight evenly into the corner posts and down to the bed rail mounting points.
Yes, every Overland cap includes our pre-wire harness with 14-gauge marine-grade wiring. The harness provides a constant 12V feed, a switched ignition feed, and a dedicated ground, all terminating at a junction point near the front window.
We also install two USB-C ports and one 12V accessory socket that tie into this harness. You can add auxiliary batteries, charge controllers, inverters, or solar input by connecting to the harness without running new wires through the cab. Optional port kits add Anderson connectors and battery monitor shunts.
We manufacture the Overland cap for full-size trucks with 5.5-foot, 6.5-foot, and 8-foot beds. Compatible models include Ford F-150, F-250, and F-350; Ram 1500, 2500, and 3500; Chevy Silverado 1500, 2500, and 3500; GMC Sierra 1500, 2500, and 3500; Toyota Tundra; and Nissan Titan.
Each cap is model-specific to match your truck’s bed rail profile and cab height. Measure your bed length from the inside of the bulkhead to the inside of the tailgate to confirm fitment. We also offer extended cab and crew cab configurations to maintain proper proportions with the truck’s roofline.
The interior walls feature horizontal aluminum channels spaced every six inches that run the full length and height of the cap. These tracks accept sliding mounting plates that you position anywhere along the channel and lock in place with a quarter-turn.
Each mounting plate has threaded holes for attaching shelves, cargo nets, tool holders, or custom panels. You can reconfigure your storage layout between trips without drilling new holes or leaving permanent marks. The track system holds up to 50 pounds per mounting point when weight distributes across at least two adjacent plates.
We use a dual-sealing system that maintains a watertight bond even when the truck frame flexes. The primary seal is an EPDM rubber gasket compressed between the cap’s lower rail and the truck’s bed rail — this gasket stays flexible from -40°F to 140°F and doesn’t harden with UV exposure.
All panel seams receive a dual-bead adhesive plus mechanical fasteners, creating bonds stronger than the surrounding composite material. The door and window frames use compression bulbs that maintain contact pressure across the entire perimeter. We pressure-test every cap before shipping to verify zero water intrusion at simulated highway speeds and heavy rain.
Installation requires two people and basic hand tools — most owners complete the process in about two hours. We include all mounting clamps, which thread into your truck’s existing stake pocket holes and hook under the bed rail without drilling.
The hardest part is lifting the cap onto the bed and centering it evenly — we recommend using a friend and taking your time to align the gasket. Once positioned, you tighten the clamps to compress the gasket and eliminate movement. You’ll also connect the pre-wire harness to a switched 12V source under the dash and run a ground wire to the chassis. Our manual includes torque specs and illustrated steps for every truck model.
The Overland cap weighs approximately 185-210 pounds depending on bed length, which is about 30% lighter than equivalent fiberglass caps. We achieve this weight reduction through the aluminum extrusion frame and composite panel construction.
Despite the lighter weight, the Overland cap maintains higher structural rigidity than fiberglass because aluminum doesn’t flex like resin-based materials. The weight savings improve your truck’s payload capacity and fuel economy while the honeycomb roof core still supports 500 pounds of dynamic rooftop load.
