his is a very rare creature! It was built for the U.S Govt by Wheeled Coach to be a National Severe Weather Laboratory. Not even 42k miles on this 7.3 diesel engine. It also comes with a 6000 watt generator with only 700 hrs. Everything operates as it should and be converted to be anything you can dream, even the two blue chairs in the back are power chairs. Speaking of the back, the box interior dimensions are as follows, 160 inches deep , 88 wide and 74 1/2 tall . New tires on all four corners. While we dont sell warranty's I do offer this.. a mechanically sound drive home no matter how far in the U.S. Should there be an unforeseen problem, I will pay for the repair or buy it back on the spot. We spend a good deal of time and effort to insure it. We want happy and repeat customers!
