I wont lie 406 family! If this little guy was available back when i was stationed up there in Great Falls i would have done a whole lot more winter camping! Here in NM i found a home with a non vehicle specific offroading group of veterans who do wheeling all year round so figured i'd get into the game.... ya'da ya'da ya'da i decided to get this stupid experience diesel heater. Mostly because the FJ Cruiser has limited space and it doesn't require any additional power source to turn the burner on and run the fan. So far I'm liking it! So far at 3/4 heat setting it Pumps out about 195degrees at the outlet vent! I just need to buy an adapter i saw to pipe it up to the rtt!
