Built to Outlast

Fiberglass construction eliminates wood framing - so there's no rot, no delamination, no structural decay. Hand-built in Ohio with molded fiberglass panels that handle 4-season camping. Low maintenance, high durability, designed for campers who plan to keep their rig for years.

Weight-Conscious Design

Every component earns its place. Solar readiness, LED lighting - the off-grid essentials without the weight penalty. Optional add-ons like 12V fridge, diesel heater, and overcab windows let you customize for your trips. We chose each feature for reliability and weight efficiency, because pounds matter when you're packing gear.

At 950 lbs dry weight, the Arctos S1 fits trucks that heavier campers can't - Ford Ranger, Toyota Tacoma, and similar mid-sizes. More payload capacity for your gear, less camper weight eating into your truck's limits. Take the same routes, camp in the same spots, with a rig that matches your truck's capabilities.
