Do RVs require generators?

Most functions in an RV do not need a generator. Lights, pumps, the furnace, refrigerator, and most electric motors operate on 12-volt DC power through the unit’s house battery. Appliances like the RV’s microwave oven, air conditioner and most TVs do require a generator or external power connection to operate. If plans are to camp for an extended period with no exterior power source, a built-in or portable generator should be considered to charge the RV’s main batteries; a solar energy system is also an option, even if to recharge batteries.
