Finally, this sums it up:
"So, rather than regurgitate a bunch of statistics that I can't independently verify, we'll use what data there is out there to make a few conclusions.
RV fires start while RVs are parked as much as when they are moving
Most motorhome fires while traveling start in the engine compartment
Most trailer fires while traveling are the result of bearings, wheels, and brakes locking up
Tire blowouts on all types of RVs can cause fires (see above discussion on Tire Failure)
When stationary, fires start due to
Carelessness (cooking, candles, unattended heat sources, etc.)
Shorts in wiring
Loose wiring connections
Refrigerator overheating and failure
For several years in a row, almost all the attention regarding RV fires was focused on RV dual power (electric or propane) refrigerators. The major refrigerator manufacturers had recalls because their cooling units were failing causing leaks, overheating, and fires.
------>It was and is a serious issue, but I think the focus on refrigerators overshadowed all the other fire causes. <<---------------
RV fires are actually relatively rare, but as mentioned above, they often result in total losses. Certainly, fires can happen to even the most safety-conscious RVers, but many fires can be prevented through common sense, inspection, and proper maintenance...."
