Hi everyone, found this on the web. www.espar.com. These units are fuel fired with an electric fan. They draw in air from outside as well as exhaust outside. This is the same as an RV furnace. It draws gas or diesel direct from the vehicle fuel tank as well as power from the vehicle battery. These are stand alone units that can be mounted in any vehicle. I will look into one of these for the rear of my coot.
