Expedition Boxes

Customizable Composite Expedition Boxes for Extreme Climates

Our Expedition Boxes are expertly crafted using high-density EPS foam and High impact FRP skins, ensuring superior insulation and unmatched durability. Designed to withstand extreme climates and rugged terrains, these boxes provide exceptional quality and versatility. Choose from a range of standard sizes or customize your own to fit your specific chassis.

Why Choose Our Composite Panels?

High-Performance Construction
Our panels are constructed with high-impact FRP vacuum-infused with high-density EPS foam, ensuring they endure the harshest elements while delivering consistent performance in any climate. Resistant to impact, scratches, moisture, and UV damage, these panels feature a 3-inch EPS foam core, maintaining an impressive R-value of approximately R15.

Durability and Moisture Resistance
Unlike metal counterparts, our high-impact FRP does not corrode or rust when exposed to water or salt, making it ideal for long-term use in harsh environments. The high-density EPS foam offers exceptional moisture resistance, preventing issues like mold and rot caused by environmental moisture.

North American Quality
All our materials and manufacturing processes are proudly produced and assembled in Canada. This ensures we deliver a high-quality, Canadian-made product with a shorter production timeline, so you can embark on your adventures sooner.

Precision Assembly for Maximum Performance

Eliminating Thermal Bridging
We use full FRP pultrusions in our assembly process to eliminate thermal bridging and reduce condensation. This ensures all FRP materials expand and contract at the same rate, minimizing stress on sealed joints and eliminating the need for maintenance.

Expert Craftsmanship
Every expedition box is meticulously assembled at our facility in Squamish, British Columbia. Our process follows rigorous industry standards, combining meticulous prepping and gluing to ensure maximum performance and durability.

Optional Upgrades for Customization
Streamline your expedition box outfitting with our optional upgrades. We handle the critical initial upgrades, including installing windows, doors, cargo hatches, skylights, and any necessary shell modifications. This ensures proper placement and leak testing, along with interior wiring channels and lighting installations to simplify your build-out. By installing necessary interior walls before adding the roof, we eliminate the challenges of post-installation modifications, saving you time and effort.

Innovative Honeycomb Panels

Our interior walls are crafted using lightweight 30mm honeycomb panels, maximizing your living space without compromising structural rigidity. These panels do not require extensive insulation and are made from the same high-impact panel skin as the exterior, ensuring a consistent and seamless look throughout your camper.

Critical Foundation

The subframe is a vital component of any expedition vehicle build, acting as the crucial interface between the vehicle and the Composite Box. We assist you in selecting the ideal subframe for your box, ensuring it meets your specific needs and budget.

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!
