  • Meticulous assembly process follows strict industry standards, with every step focused on strength, weather resistance, and longevity.
  • Built to outperform in rugged conditions. This is the last camper box you’ll need.

We only work with high quality marine grade puck lights and Rigid scene lights.

We recommend having lighting installed as part of the composite box assembly process. Running wiring and placing each lights location is a much easier process when working with flat panels, this way you are prepared to start your build as soon as you receive your box.

Marker lights will be installed to DOT requirements.

DOT Marker Lights

Marker Light packages suited to DOT standards. We will install the proper package for your weight rating and box type.

Scene Lights

Our exterior lighting option. One of the top choices in the industry, Rigid Industries Scene Lights produce 1100 raw lumens with minimal amp draw.

Interior Puck Lights

Our top choice for high quality puck lights are Skandvik. We provide wire chasing through the roof panel during assembly with additional wire left inside to be run to the final power source.

Roof fans, vents and skylights are helpful for air exchange, lighting, temperature control, and evacuating odors and moisture. We recommend at least one vent for most builds, but more may be desirable for some purposes.

Having these items installed during the composite box assembly process is recommended as they require large
holes to be cut in the box and in some cases wiring run through the ceiling panel. Allowing us to complete this step ensures your components are properly places and leak tested.

Maxxfan Deluxe

This Maxxfan is a Powerful 10 speed reversible fan with thermostat to control room temperature. The built-In rain cover provides full time protection, while the fan is on or off.

Maxxfan Dome

This small Maxxfan is enough to pull air out of a regular size camper. Note that this model fan only exhausts air out, and cannot be reversed to pull fresh air in. Typically used for wet baths or if roof space is limited.

Manual/Electric Skylight

Both the manual and electric skylight are great for ventilation and added lighting in smaller spaces.

Both models are equipped with additional LED lighting.

Fastgun Turnbuckles

Fastgun Turnbuckles are our recommended tie down option for flat deck boxes. These turnbuckles come in assorted lengths to make sure we can mount to a fixed point on the deck.

Camper Jacks Manual/Electric

We offer a manual crank option, and an electric option. If your box is going to be removed often, we highly recommend the electric option.

When choosing a solar solution, there are a few options:
Solar panels that can be mounted to the composite box or brush guards, or folding portable kits.

Our Rigid solar panels provide efficient and reliable power. With this installation we include a bundle of 10AWG wiring ran through a sealed entry gland for you to connect with your electrical set up.

Folding portable kits are lightweight and flexible, allowing you to park in the shade and set up solar power wherever you go. We will install a solar port on the side of the composite box to avoid running wires through a door or window. Foldable kits are sold as parts only.

Our panel of choice for interior walls are built using lightweight panels that incorporate the same FRP high impact exterior with a honeycomb foam core. Interior walls add to the structural integrity of the camper and provide additional rigidity. These panels can be used for bed structures, storage, wet baths, etc.

Testimonials

The team at Off Grid Customs assembled and mounted a 15′ Total Composites custom habitat shell onto my fuso 4×4 truck. I am now in the process of fitting it out for my future journeys. They did a really good job on it and I would be happy to use their services again for any kind of camper build work that I could not do myself.

The folks at OGC are experts in what they do, and it’s been well worth the investment knowing that my camper and all the features inside/outside it are very well made. Even in the hot desert, my dog and I can be comfortable inside the camper with the windows open and fan running.

The crew at Off Grid Customs is friendly & helpful. They picked up my truck camper shell and I cannot be happier with the quality of their work.

We’ve already put over 5,000 km on the truck with the new camper shell, including driving through the Rocky Mountains in the winter. The entire camper shell and the optional items are rock solid. It’s amazing how warm the camper is in the winter.

Awesome and professional service! Loved working with Allan and everyone there. I would recommend them to anyone wanting the best craftsmanship around!
