Ok, so he's using an air compressor air tank for the propane? I'd say this has not been DOT approved and I would be skeered sheetless to put my family in the thing. The shelf for the air compressor gear is still on the side of the tank, maybe he likes using it for the far back seat kiddo to set their clutter on?
Also, the fill for the propane is under the rail, I could remove that in the first ten minutes of any off roading I would do.
So I have to balance this with positives cause I don't just want to shoot it down---I could adapt a connector to run the heater in our travel trailer, plus I'd be set up to bar-b-que any place I took it!
