1. The RV Doctor and RV 101 are NOT always the best source for correct information
2. The refers are DESIGNED to be run in transit. The LP systems are DESIGNED to be ON in transit
3. There have been tens of millions of RV's (motorhomes)in transit with their Refers ON over the past 50 years. I will bet you cannot find more than 10 that have had a fire CAUSED by the refer being on, when fueling either LP or Gasoline.
4. This is a horrible thing to happen, but it happened because the LP fueling station did NOT follow correct procedures for using LP.
5. I REPEAT--- IT HAPPENED BECAUSE THE LP STATION DID NOT FOLLOW CORRECT PROCEDURES FOR USING AND FILLING LP. PERIOD. Doug
