Custom Adventure Camper

The Mountaineer

A trail-ready camper where off-grid capability still feels like home.

Platform: Custom camper van
Purpose: Adventure travel
Build: Full custom conversion
Home base: Phoenix, Arizona

The Brief

Comfort had to keep up with the route.

The Mountaineer was planned as a true travel cabin: a flexible place to cook, gather, sleep, wash up, and recharge without making the owners choose between comfort and the next trailhead.

The floor plan centers on a convertible bed and custom upholstered lounge, preserving a generous galley while hiding the shower and toilet until they are needed.

Exterior additions—including a roof rack, Flarespace bump-outs, and a retractable step—extend the useful footprint without crowding the interior.

One Space, Many Modes

A camper that changes with the day.

Cooking, lounging, washing, and sleeping share one compact volume. Each function has a clear place, and the pieces that do not need to be visible stay tucked away.

Off-Grid Package

Power, water, and heat for longer stays.

The systems package was sized to support daily living away from hookups while keeping controls and service points understandable.

A flexible table turns the lounge into a dining or work zone.

The convertible seating is shaped for everyday use, not just the drive.
