Thinking about converting and ambulance to an RV

Not sure how tall you are, but ambulances are usually pretty short. I'm 6-04 and can't stand up inside one. They are pretty narrow as well, won't be very much room inside. They often aren't insulated, but rather depend on robust heating and cooling systems, powered by "free" fuel. They don't have water systems, or sewer systems... nor much room underneath to add them.

Seems like it would be a waste of money to me... but what do I know.
