This is a deluxe work van with ONAN generator and OVERHEAD air conditioning! Now you can work in comfort regardless of the outside tempature. I don't know what AT&T used this van for but evidently they needed air conditioning and 110 AC voltage because they installed a top of the line Onan generator in the side of this van. Everthing works great and the van drives perfect. This is another of AT&T's retired fleet vehicles that I have been selling for the last few months.
