Question: Is that a 100 gallon propane tank or 100 pound propane tank on your rig? I'm thinking it's the latter. Propane weighs about 4.24 pounds/gallon so you can do the conversion either way. My guess is you have a 28-30 gallon LP tank.
Not that it matters, it will power the refrigerator by itself for a good long time.
We run the generator if we need air conditioning or power for other things while travelling down the road, so the refer gets AC power along the way as a result. If we don't run the generator, then we'll put the refer on propane.
Have a great trip.
