Any downside to a domestic refrigerator?

Hi! Please never hesitate to ask a question--none are too basic--that's is how we all learn! Most RVs with household type refers use an inverter system to convert 12 volt DC to 110 AC. They also have increase battery bank sizes to supply ample current. There is usually a generator also that supplies power. This setup doesn't allow much boondocking (parking without full hookups), but then a lot of people with big rigs and a household refrigerator don't boondock much anyway. Hope this helps and good luck--just remember--if Mama ain't happy, nobody is happy!
