Complementing the Made in U.S.A drivetrain are two Mercedes-Benz Unimog U1300 axles that spin 44x14.50R20 Alliance tires on 20x9-inch steel wheels. Daniel's Jeep can cruise at 60-65 mph, and the top speed is 83 mph. "It actually rides nice, but it's loud-really loud!" Daniel says. When pure torque and traction aren't enough to get this World War II olive-drab-green machine around, over, or through obstacles, this Jeep has three winches to drag it the distance.
Built for European off-road rallies, the 8,300-pound M715 is still undergoing development. The Jeep now sports seats from an '01 Grand Cherokee, a full rollcage, and coil springs to replace the original air springs. Future plans call for bead-lock wheels, an exo-cage, new soft top, bed storage, a transfer case with PTO provisions, and a twin motor Bow winch.

These Unimog axles have geared hubs that multiply the torque available at each wheel and provide unmatched ground clearance and strength. |  There's a second '98 GMC 3500HD...  There's a second '98 GMC 3500HD radiator behind the cab to cool the engine and transmission, even when the truck is in deep mud. In the early stages of the buildup, the 4L80E transmission was converted to full manual control (eliminating the need for a computer) and an aluminum GM adapter was modified with a steel plate to mate it to the Ford transfer case. |  The axle position dictated...  The axle position dictated that the Cummins engine be set back almost completely behind the front axle. The Unimog U416 steering box and 12,000-pound-capacity winch meant there would only be enough room for a relatively small aluminum radiator behind the grille. |
