I've been reading the various Class B Forums for a few years now and have never
read of a fire related to normal use of the furnace in a Roadtrek. The furnace in the 2004 Roadtrek I owned had the furnace in basically the same place "under the twin bed on the curb side
The only complaints about the furnace (other than noise
) that I've read is that people would like to direct the heat out from under the bed.
Some good posts on modifying that are here:
