Electrical hookups in campgrounds or by generators. Generators are optional equipment on all but the very largest and most expensive RVs. With a generator, most or all of the electrical equipment on an RV can be used, even when the RV is parked in the middle of the desert. Generators can also be used to charge a dead engine battery. RVs with air conditioners will often need to use a generator to use the air conditioner. Unless an RV is equipped with a power inverter, a generator is also needed to power a microwave and other power-hungry devices like blow dryers. Most RVers these days opt for an air conditioner. All but the longest RVs will have one unit, normally on the top of the RV. Long units — those over 35 feet — may have two. Some new model RVs have sleek, low profile central air conditioning systems. RV air conditioners need a lot of power, and so cannot be operated except when the RV is hooked up to electricity in a RV park (many public campgrounds with hookups do not provide enough juice to run an air conditioner), or when the RV's generator is in operation. If an RV does not have an air conditioner, one can be easily installed. Most RV dealers as well as Camping World sell and install them. Most RVs these days have a propane-electric powered furnace. Propane fuels the flame, providing the heat, which an electric fan circulates throughout the RV. Most RVs have a thermostat just like in a regular home. Some RV heaters are in the same unit as the air conditioner, which may be on the ceiling. RV furnaces will keep an RV very cozy. Some RVers carry a small electric heater to run when hooked up to utilities, saving themselves propane in the process http://www.newrver.com/basic.html
