This can be a hot button topic online. Many say “no big deal we do it all the time for years and years”. And some say “you're going to burn up in a fiery death”. Truth is, there's not a lot of data showing a preponderance of propane fires on the road. While it's obviously a safer move to shut off a fuel source while traveling, we traveled with our propane on for about a year before we upgraded our batteries with enough Amp Hours to handle running the fridge on our inverter for a whole travel day. Now, we run in electric via the inverter and monitor our batteries from the truck with the BMV-712.
