## More About This Hauler Truck
This is not your typical Schwalbe. While most conversions were equipped with the smaller 8.3L or 10.8L Cummins engines, this truck features the highly desirable 15-liter Cummins X15. Professionally tuned by PDI in St. George, Utah, it delivers approximately 600 horsepower and nearly 2,000 lb-ft of torque, providing effortless towing performance whether pulling through mountain grades or cruising the interstate.
Built as a rare stretch conversion, this truck offers three rows of seating, substantial in-bed storage, and the premium amenities that have made Schwalbe haulers legendary among serious RV, horse trailer, and motorsports owners. Trucks equipped with the X15 drivetrain were produced in extremely limited numbers, making examples like this increasingly difficult to find.
The interior presents exceptionally well with premium black leather seating, woodgrain trim throughout, and a comfortable layout designed for long-distance travel. The rear seating area converts into a bed, making overnight trips and extended hauls far more convenient. With its powerful drivetrain, luxury accommodations, and proven reliability, this truck represents one of the most capable Schwalbe stretch haulers available today.
## Towing Ability
With approximately 600 horsepower, nearly 2,000 lb-ft of torque, and a fully air-equipped chassis featuring air ride suspension, air cab, and air brakes, this truck was built to tow heavy loads with confidence. It is currently configured for air ride gooseneck hauling and can be converted to an air ride fifth-wheel setup for $1,500. Whether you're hauling a large horse trailer, luxury RV, stacker trailer, or heavy equipment, this truck has the power and stability to get the job done.
