1. They are designed to run on LP while in transit
2. IF you have a blow out problem, there are kits and fixes for that problem
3. You should NEVER smell LP inside if the flame goes out. The LP is shut OFF after the flame blows out. BUT, If the flame blows out, the refer will AUTO relite.
4. If you smell LP you need a Manometer test to confirm there are NO LP leaks in the LP system
5. They do make 3 way RV refers. But, they are very rare. The 3rd way is a 12 volt Heating Element that runs when the engine is ON to supply enough 12 volt current to run the 12 volt element. This is a Maintainer that only keeps the refer at the cold you started out at. It is not designed to cool the refer down.
6. You can install a 1000 or larger Watt Inverter to run the refer on 120 while in transit. The 120 element pulls about 350 watts, but I believe if you go the Inverter route to go at least 1000 watts or higher.
7. You are talking to the wrong people at RV dealerships. If this is the best answers you have received, I would AVOID those dealers for my service work and advice. Doug
