Solid sides, closed

Solid aluminum sides

What's in the bed stays your business.

Solid aluminum gullwing doors put a wall between your gear and the parking lot. Trailhead, jobsite, hotel lot — nobody sees the tools, the camera cases, or the recovery kit until you open the door. Same shell, same roof, same locks as the glass version; just nothing to look through.

Solid sides — nothing to see

Same shell, solid panels

Doors up — full access

Full gullwing access

Everything within reach.

Two full-length gullwing doors plus the rear door open the bed from three sides. Gas struts hold each door up on their own, so the cooler or toolbox pushed against the cab is an arm's reach from the curb. Nobody crawls into the bed.

6 locking points

Six-lock security

Lock down the whole bed.

Six locking points cover both side doors and the rear door. Close it up and your tools, recovery gear, and camping equipment sit behind locked aluminum — not a snap-on cover.

T-slot rails

Crossbars

Roof rack

Rooftop tent

Two full-length T-slot rails

Full-length T-slot roof · 450 lb dynamic / 850 lb static

Build above the bed.

Two T-slot rails run the length of the roof. Crossbars, a rack, a rooftop tent, an awning, solar, a bike or kayak carrier — anything with T-slot hardware bolts on, slides where you need it, and comes off clean. Rated 450 lb driving and 850 lb parked: a two-person tent, the people in it, and the gear on the rack.

Door storage · interior expansion points

Doors and walls, ready for your build.

The inside of each gullwing door is a flat, rigid aluminum panel — mount a MOLLE board, a tool rack, or a camp-kitchen shelf and it swings up and out with the door, right where you're standing. Inside, rivet mounting points are already in the roof and both side walls: lights, storage panels, shelves, bolt on without drilling through the shell.

Door panels: tools and recovery gear on one side, camp kitchen on the other
Roof and side-wall points: interior lights, MOLLE and storage panels, shelving

Road tested. Canada tested.

Built for years outside.

Every design gets road tested — vibration and wind load at highway speed — then goes through a Canadian season of deep cold, high humidity, and freeze–thaw swings, to see what the seals, doors, frame, and fasteners do. And because the shell is aluminum, not steel, there's no red rust waiting under the paint. Rain, snow, road salt, coastal air: that's what it was built for.

Bed-rail clamps — no drilling

Installed in a driveway

Aluminum shell, sealed seams

Built for DIY · no drilling

Easy to build. Sealed by design.

One bolt size runs the whole cap — M8 at every joint, one socket in your hand. The critical seams arrive with 3M sealing tape already on the panel: line it up, torque it down, and the joint is fastened and sealed in the same step. Then it clamps to the bed rails. No holes in your truck, and it comes off the same way it went on.

Two people, a socket set, and your driveway
Modular by design: doors, panels, glass, and hardware are individual parts — damage one, replace one, not the cap

Work-ready, solid sides

Work & adventure ready

Work all week. Adventure all weekend.

Monday it's a locked, dry, walk-up tool room on the back of the truck. Friday it's base camp — same cap, same locks, nothing to swap.

Questions

Frequently Asked

How long does installation take?

Most customers complete the install in about 1–2 hours with two people. No drilling is required — the cap secures to your existing bed rail holes with the included mounting clamps. An install guide is in the box.

Does it come with side windows, or is it solid?

We build both versions on the same 6061-T6 aluminum shell — same load rating, same bolt-on install. The difference is only the side panels:

Windows — tempered sliding glass on the driver and passenger sides. Better for overlanding, camping, pets, or any time you want airflow and outward visibility.
Solid — fully enclosed aluminum panels. Better for job-site tool security or gear you want out of sight and keyed-locked.

Will it fit my truck?

This cap is cut for the specific year, make, model, and bed length listed in the fitment box at the top of the page. If your truck matches that spec, the cap is engineered to bolt right on. Short-bed and long-bed versions are not interchangeable.

Will the aluminum rust or the powder coat fade?

The shell is 6061-T6 aluminum — corrosion resistance is inherent to the material, so the structure won't rust. The exterior is finished in powder-coated black for UV protection. Even if the powder-coat gets scuffed at a job site, the aluminum underneath stays sound. If you ever have a structural concern, contact us at info@tkmauto.com and we'll work with you directly.

How does shipping work?

Free freight shipping in the continental US, from our California warehouse via LTL carrier. Delivery requires a signature; the carrier will schedule a window once it reaches your local terminal. A phone number is required at checkout so the freight carrier can reach you to schedule delivery.
