Never had a refrigerator problem on any RV I've owned since the early 1970s. Guess I've been lucky so far. If I do ever find myself having to replace the unit, I will stick with the gas/elec unit. We run the gas when traveling and run it on gas for a day or two before leaving on a trip.
If I have a job on the TT [addition or repair] I will run it on gas so I will have something cold to drink while working. It will run for a long, long time on a 20# tank. We have two 30 lb tanks but I use an extra tank to run it while at home or storage.
