More About This Hauler Truck This 2012 Freightliner Sumit Hauler isn’t just any truck—it’s a factory-built, fully loaded hauler in exceptional condition. Unlike some home made aftermarket conversions, this truck maintains the original Summit Hauler integrity and the M2-106 body shape that’s still current in 2026 models. The interior is in excellent condition, featuring air ride captain’s chairs, rear seats that fold down into a bed, and multiple charging ports including USB, 110V, and lighter ports. Previously owned by someone downsizing their setup, this truck offers an opportunity to upgrade, trade in, or step into a late-model SportChassis for a fraction of the cost of new. With a rust-free southern Texas truck and DEF/DPF emissions compliance, it’s ready to haul safely and comfortably nationwide for years to come. Towing Ability Equipped with full air ride suspension, air ride cab and seat, and hydraulic brakes, this Summit Hauler is perfectly set up for smooth towing. Currently configured for gooseneck hauling, it can be upgraded to a Hensley air ride fifth wheel for $4,950, making it an ideal truck for trailers of any size. With 350 horsepower and over 1,000 lb-ft of torque, this truck handles mountain passes, highway loads, and long hauls with confidence. Kitted out with super single Michelin rears, this is a one of a kind truck on the market.
