Can I run my RV refrigerator on propane while driving?

RV refrigerators work best when using propane but 3 way refrigerators can be run on 12volt Dc while driving. This conserves propane but will drain your battery if you switch your motor off for even a few hours. If you travel with your propane on, turn it, and all other appliances off before going into a gas station.
