So, in hooking up to my main tank, it would obviously be lower than the heater up in the truck, so would a person then need to add a booster pump, or does the supplied in line pump have enough oomph to get it done? In reading on the Wastabo heaters, it sounded as though they ran continuously which would sure put a draw on the batteries. Almost made up my mind to save up my money and go for the German made unit over a Chinese on account of the fact that I'd really need something reliable. Even contemplating a small marine application diesel heater which is about twice the cost of the parking heaters.
