We had a 5th wheel fire here in the RV park I live in in metro Phoenix. Wife got out, husband got it out with his extinguisher and a neighbor's. His inverter caught fire. When he woke up place was filled with smoke, smoke alarms didnt go off. New inverter installed (professionally) and I'm hoping new alarms and fire extinguishers. 2 fire trucks and 3 police cars showed up. Most neighbors slept through it.
