More About This Hauler Truck
This is not your typical Schwalbe. It is not the common 8.3 Cummins, and it is not the smaller 10.8 big motor option either. This truck is equipped with the much more powerful 15-liter X15 Cummins, delivering massive torque and effortless pulling power in any terrain. Built as a hard-to-find stretch model, it offers three rows of seating, huge in-bed storage, and every desirable option you could want in a premium hauler. This truck features the Thermo-King tri-pac system, as well as a rooftop Dometic AC system.
The interior is truly as new, showing little to no wear, with stunning black leather, rich woodgrain accents throughout, and an incredibly comfortable layout. The rear seat folds down into a bed, making this truck perfect for long hauls, shows, or extended travel. With Schwalbe producing so few of these trucks, this represents one of the best opportunities to own a big motor Schwalbe stretch compared to a new one at over $330,000, it is an absolute steal. There are no true comparables on the market.
