This thing puts out really good heat for the money. I'm using this thing for camping out of a roof top tent. Added a lawn mower fuel filter to the fuel line, fiber glass wrap to the exhaust, and hooked a ventilation hose up to run it into my tent and good to go. Haven't camped over night with it yet but did a 6 hour test run on it to see how everything works. Really warm heat! Directions are tough, controller isn't user friendly but simple enough to figure out. Make sure you prime it before using it. And if your hooking it up to a solar/battery generator. You may need to get a convertor. I have a Jackery and it wouldn't start up on the d/c side. Pulls to much power to start. But once it's running it has a very minimal power pull. Once I plugged it in on the a/c side ran like a champ.
