I have seen one with an RV type air conditioner placed on top of it. This was at a dog show. The size seams perfect for a dog show van. I am wondering if the engine would be suitable to making long trips...... and possibly run the engine while standing to run the air for the dogs in the back.... maybe for 1-2 hours? I can do that with my Sierra, but that truck is to huge for some of the trips I make.
