My husband and I purchased a trailer home that had been left empty and open to the elements for over 2 years. We have rehabbed alot of it, but are having issues with the furnace. We are considering converting to an outdoor furnace. Has anyone else done this? How well did it work? What is the best model to use (the house is only 12x70). The idea was to convert, heat with it, and also use it to dispose of most trash, then use the ash in the compost heap. Any suggestions?
