2004 Stewart & Stevenson 6x6

This 2004 Stewart & Stevenson M1088A1 6×6 military truck was purchased with the intent of outfitting it for overland travel. Starting with the chassis, the owner began upgrading a variety of components including the suspension and fuel tank. He also installed a 16-foot Total Composites habitat with a queen-sized bed platform. But unfortunately, due to the Covid-19 pandemic, he has changed his plans and listed this truck for sale in the Expedition Portal Forum classifieds.

Given that the habitat of this truck has not been built out yet, this is the perfect opportunity for a new owner to make this truck exactly what they want. Think of it as a blank slate to make your own.

From the Seller

When combined with a 4-season habitat, the MTV is a go-anywhere haul-anything basecamp. Fun and easy to drive, it fits in my driveway next to my Tundra. The composite box is completely bare inside but it does include window shades and screens with blackout covers and a queen-size bed platform that have all been installed. This 16-foot Total Composites Habitat box is ready for interior buildout. The cab is also ready for carpet, headliner, and finishing. The truck runs and drives flawlessly and is painted red under the vinyl wrap.

The MTV or medium tactical vehicle family are all based on a common chassis; the Austrian Steyr 12M18 truck. After heavy modification to meet a US Army mandate of 50 percent US components, 17 variants of the truck were designed and manufactured by the likes of Stewart & Stevenson, Armor Holdings, BAE Systems Platforms and Services, and most recently, Oshkosh Corporation.
