Built to explore California, Nevada, and Arizona, this 1976 GMC K25 pairs original orange-and-white paint with an Alaskan camper, extensive period upgrades, and an unusually detailed record of its development. Its original owner was an engineer who spent years shaping the truck into his vision of a backcountry travel rig, documenting the process through receipts, blueprints, and assorted records. Today, it’s offered by a private seller in Huntsville, Alabama, as a non-running restoration project with a compelling history.

According to the seller, the accompanying archive spans thousands of pages. Highlights include a 1987 receipt from Montague Off Road in Buena Park, California, totaling more than $15,000 for work involving the front axle, shocks, springs, axle trusses, and motorcycle mount. A separate receipt documents a rebuild of the original 400ci V8 in 2000.

The truck reportedly has been parked since 2001, when its original owner and builder passed away. The subsequent owner purchased it from the estate in Nevada and later brought it to Alabama, where the current seller acquired it locally last year. The truck needs a thorough mechanical assessment and recommissioning, and the Alaskan camper requires restoration.

Original 400ci V8: A receipt documents an engine rebuild in 2000, prior to the truck’s extended storage.
Extensive build archive: Thousands of pages of documentation, receipts, and blueprints reported by the seller.
Period off-road upgrades: A 1987 receipt exceeds $15,000 and details front axle, suspension, axle truss, and motorcycle mount work.
Original orange-and-white paint: A distinctive two-tone combination on a truck the seller describes as very solid.
Alaskan camper: Equipped with opposing lounge seats, wood cabinetry, a galley, and a portable toilet.
Southwest history: Built for exploring California, Nevada, and Arizona, with accompanying historical campsite photographs.
Restoration project: Non-running, with the fuel tank currently removed and a new replacement tank included.

This K25 offers a window into a carefully developed adventure build from well before overlanding became a familiar category. Its original owner invested considerable time and money in preparing the truck for travel, and the surviving paperwork offers the next caretaker an opportunity to understand how the rig came together.

The 1987 Montague Off Road receipt is a particularly interesting part of that history. It records more than $15,000 in work addressing the truck’s axles, suspension, reinforcement, and equipment-carrying setup. Together with the blueprints and other records, it could provide valuable guidance when assessing the modifications and planning the restoration.

The photographs add another dimension to the story. A historical image shows the GMC at a campsite with the Alaskan camper raised, while current photos reveal the living quarters and their period fittings. For someone interested in bringing an older expedition-style truck back into service, there’s an existing vision here worth exploring.

Exterior & Chassis

The seller describes the truck as very solid and retaining its original orange-and-white paint. Its square-body profile, substantial front brush guard, and Alaskan camper give it a distinctive period appearance.

Documented work includes upgrades involving the front axle, shocks, springs, axle trusses, and motorcycle mount. The accompanying records should be consulted for the specific components and scope of those modifications.

Please note: The truck will be sold with the smaller silver wheels shown in some photographs. The white steel wheels and STA Superlug tires pictured are excluded from the sale.

Alaskan Camper & Living Quarters

Inside the Alaskan camper, opposing upholstered lounge seats sit toward the front, with an opening between the living quarters and truck cab. Wood cabinetry, drawers, and floor access hatches are visible throughout the interior.

The compact galley includes a stainless-steel sink with an integrated drainboard and a stove/oven. A portable toilet sits near the rear entry. These fittings give the interior the character of a self-contained traveling setup built around the original owner’s needs.

The camper requires restoration, with visible wear to the upholstery, cabinetry, and interior finishes. The supplied information does not establish the operating condition of the appliances, plumbing, electrical equipment, or camper lifting system.

Documentation & Ownership History

According to the seller, the original owner was an engineer who compiled thousands of pages of receipts, blueprints, and assorted documentation during the truck’s development. Notable records include:

A 1987 Montague Off Road receipt totaling more than $15,000
A receipt documenting a rebuild of the original 400ci engine in 2000
Build-related blueprints and supporting records
A historical photograph showing the truck and raised camper at a campsite

The truck reportedly was parked following the original owner’s passing in 2001. Its next owner acquired it from the estate in Nevada and subsequently relocated to Alabama with it. The current seller purchased it locally last year.
