The vast majority of us RVers do it that way. If the refer is set to "Auto" it will prefer shore power but when that disappears, it automatically switches to propane. You can get it cool at home, on electricity/propane, before loading, then keep it cool on propane until you get to the campground where shore power, if available, will take over once again.

Be aware there are situation where you have to turn off all propane usage (tunnels, ferries) but the refer will not lose too much coldness. Some don't travel with the propane off. Leaving it off while traveling will not cause a significant temperature drop if the contents were cold already. The popular reason for turning it off while traveling is the
concern about a propane line breaking along the way. However the safety valve in the pigtail will shut off the flow if the line is compromised.

Bottom line, lots travel with it on, some don't. It is up to you.
