The Dometic and Norcold RV Refrigerators are a BIG source for RV fires. I know this first hand as this past September my neighbor woke me at 2:30AM on a Saturday and said Mr Barnett your Bus is on fire. By the time I got some clothes on and got out the back door of our home the local fire dept was waiting on me and the fire was exiting the roof of the bus above the fridge. The heat from the plastic burning in the fridge was so hot it burnt a hole in the roof of the bus about 3 feet in diameter. If this had been a SS coach it would have burnt to the ground with all of the fiberglass in those units. With a bus and all of the metal the fire dept was able to save the coach where it was still drivable but thanks to National Interstate Insurance Company they totaled it due to the structural damage, water and smoke damage. Check out the
www.copart.com web site and look at all of the RV's they have on there and most are from fires. (It only took the fire dept 2 minuets to be on the scene after they received the call)
