A 5-ton military truck that once hauled semitrailers for the U.S. Army is now an 11-meter camper capable of sleeping an entire family. This 1990 BMY M931A2 was converted by Plan B Trucks, a Utah company specializing in turning heavy-duty trucks into expedition vehicles.
The result is a rare blend of military-grade engineering and modern RV comfort, complete with two double beds, a shower, and air conditioning. But what makes this build truly special is that it retains its original military drivetrain and 6x6 traction.
From Battlefield to Family Adventures: The BMY M931A2 Story
The M931A2 is the tractor-trailer version of the U.S. Army's 5-ton 6x6 vehicle series. It was built in Marysville, Ohio, by BMY, a division of Harsco, and according to Silodrome, it weighed about 19,895 pounds (9,024 kg) empty.

Designed to pull semitrailers over rough terrain, the truck was engineered for durability rather than comfort. In 2017, Plan B Trucks took on the challenge of transforming this military workhorse into a livable camper.

The Conversion Process
The team added an 8.2-meter habitation module, bringing the total length to nearly 11 meters from bumper to bumper. Despite the added living space, the truck's mechanical components remain largely untouched.

This means the owner essentially has a true off-road machine rather than a camper body on a highway chassis. It's a vehicle that won't shy away from mud or snow. The longer history behind the story is traced in Galician Fishing Boat Genesis Splits in Three After Orkney Grounding.

Why This Conversion Matters for Overlanding Enthusiasts
This military truck camper represents a growing trend in overlanding: repurposing heavy-duty military vehicles for civilian adventures.
