I hear about RV'ers boondocking at WalMart all the time. How do they run everything without hookups ?
A modern class A is a self contained unit. The on board generator will provide electricity just the same as plugging into shore power will.
It will also have a bank of "house batteries" that provide 12 volt power, and usually an inverter that will take the 12 volt battery power and change it into 120 volt AC. With enough battery capacity you can run everything that you need, Except air conditioning, overnight from the batteries. If air conditioning is needed you must run the generator. The batteries can be recharged by running the generator as needed.
Okay, so the generator supplies all the electric. So when would the batteries be used, and why even use the batteries if the generator supplies all needed electricity?
