The folks over at 4-Wheel & Off-Road turned a well-used airplane tug truck into a killer off-road machine while keeping it street legal. This project was done over nine Herculean days before the so-called Ultimate Adventure 2014, and the team over at Drive Dirt Everyday has kindly documented the whole build process on video.
The vehicle started life as a 1990 Dodge tug truck that hauled around airplanes for a living. The team kept the Cummins six-cylinder diesel, but tossed out almost everything else replacing the stock parts for either custom one-off fabricated parts or custom heavy-duty parts. The build process certainly looks like a ton of work, but the end result created one fantastic crawler. Check out the video above.
