This 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 33k miles on this 6.0 diesel engine. It also comes with a generator. 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, 13 ft deep , 88 wide and 74 1/2 tall . While we dont sell warrantys 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!
