I bought this for camping in my truck camper. I hooked up the unit according to the directions and tested the unit. This gets very hot while running. 260 degree output air and exhaust temp was 340 degrees. The issue is the unit leaks diesel fuel all over. I think I got a bad unit since I have not come across this in reviews before. I tried to contact customer service but can not request a refund since the process requires a picture in a different format then my phone takes. I can send jpeg photos and it wants something else. This is very frustrating since I planned to use it for my camping trip coming up. I do not trust the item since I can see visible fuel leaks on the ground, enough to make me think twice about it. I'm glad I didn't install it and have it leak all over my camper.
