Propane powered AC?
Since the fridge can run off propane; why can't a roof mount AC be ran off propane?

I suppose one practical approach (more practical than a whole-RV absorption air conditioner, at least) might be to modify a truck reefer unit by replacing the little diesel engine with a propane-fueled engine. It wouldn't have much if any advantage over a propane fueled generator and traditional electric air conditioner except possibly being a bit more efficient overall (due to avoiding the conversion from mechanical to electrical energy and back again).
