Step into a true classic diesel Class A motorhome with this 2003 American Dream M-40U — a spacious and powerful coach designed for year-round travel, big families, and seasoned RVers alike. Built on a Spartan® chassis and powered by a robust Cummins® 8.9L diesel engine with 370 hp paired to an Allison 6-speed automatic, this rig delivers smooth highway performance and long-haul confidence.
At 40 feet long, the M-40U offers generous living space with thoughtfully designed interiors that feel bigger than the footprint suggests. With ample tank capacities — including 150 gallons of diesel fuel and over 90 gallons of fresh water — you can roam longer between stops. The coach’s heavy-duty build features a high GVWR of approximately 33,700 lbs and strong towing capacity, making it easy to bring a towed car, trailer, or outdoor gear.
This motorhome’s combination of power, space, and utility makes it ideal for everything from cross-country adventures to full-time RV living. Classic finishes, dependable diesel performance, and rugged Spartan construction give the M-40U a timeless blend of comfort and capability — all backed by American Dream’s reputation for quality and road-ready engineering.
