Christmas is here!! So the next thing our on bus conversion is a diesel heater! Not only did santa throw up in the bus, but we finally got the cozy warm grotto we've always wanted!

Trucks with a 6.7L Cummins engine have a block heater built in, so if you live in an extremely cold climate, you'll want to know where it's located.

As winter sets in and temperatures drop, a functioning heater becomes a necessity. But what if, instead of warm comfort, your heater blows icy air through the vents, or fails to work altogether?
