With 450 horsepower and 1,450 ft lb of torque, this pre-DEF M2-112 delivers effortless power that newer emissions trucks simply cannot match. Being one of the last years before DEF, it avoids all modern emissions headaches while offering the reliability these trucks are famous for. Finished in a glossy white exterior paired with a factory tan leather SportChassis interior, this truck presents extremely well for its age and miles. Mechanically, it is rock solid and runs down the highway exactly as it should, with noticeably more power than standard M2-106 SportChassis trucks. It was meticulously maintained by a private owner who relied on it to haul a race car team across the country, where reliability and on-time performance were critical. Aside from a few minor stone chips and very light entry wear, this truck is in excellent overall condition. With its million mile drivetrain pedigree and clear history of proper care, it is ready for many more years of dependable service. These M2-112 SportChassis trucks were produced in far smaller numbers than M2-106 models, making clean examples like this increasingly difficult to find. New, a comparable truck would exceed $320,000 and still come with DEF and emissions concerns, making this an absolute steal by comparison. Towing Ability This M2-112 is set up for gooseneck hauling and is built to pull large horse trailers, race trailers, campers, and heavy equipment with confidence, even through mountains and long grades. With over 100 gallons of diesel on board, long-distance hauling is easy, often allowing extended ranges between fuel stops. For buyers wanting the ultimate towing comfort, an air ride fifth wheel hitch can be added for $3,800.
