The Arctos S1 brings Grumpy Bear's full fiberglass construction to a new price point - without compromising what makes us different. Hand-built in Ohio, off-grid ready from the factory, and engineered for campers who understand that weight matters and quality lasts. This is fiberglass truck camping, refined.
Full fiberglass construction at estimated 950 lbs dry weight means more payload for your gear and less worry about your trucks limits. The Arctos S1 fits mid-size trucks like the Ford Ranger and Toyota Tacoma - opening terrain that heavier campers cant reach.
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.
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.
