Planning on using the electric.
Question is - Is it running off the house batteries while driving and is the engine alternator enough to keep the batteries charged and operating the refrigerator while traveling.
Thanks for your help / advise.

The 'electric' source for the fridge is 110 shore power. Your fridge is a duel fuel source unit (batteries are not the fuel source). You will always need the 12v house batteries for the electronics no matter if you use Propane or shore power 110. It is very standard to drive (or pull) a camping unit with the propane on for the fridge when traveling down the road. It is good that you are not 'comfortable' using propane while driving. I commend you. All who take to the roads should always have the hazards of this in the forefront of our minds. Read up on it and talk to other camper users and your comfort level will increase. Check your equipment around the fridge to make sure that the flow pipe is clean and not obstructed by any wasp nests or spider webs. imo, you should have no worries driving down the road with the propane on ( I have done it for over 30 years). If you go into a filling station, that would imo be the only time that I would shut the 12v switch off at the fridge. shutting the 12v off will close the propane off at the fridge. when done filling, pull forward a little to get away from any gas fumes and turn on the 12v. You should hear your propane come on. I have never shut my fridge down when fueling, as I use Diesel and there is no fumes to ignite.
