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.
Propane powered appliances are always supplied from your on board tank.
You will have a fresh water tank that you will have filled from some source prior to arriving at the boondocking location. ON my rig, the fresh water tank holds 100 gallons. You will also have waste water holding tanks, both black and grey, that should be sized to contain all of the fresh water that you are carrying. You will need to make sure that these tanks are empty when you arrive.
The fresh water system has a pump that is powered by the 12 volt batteries that moves the fresh water from your tank and causes it to come out of the various faucets.
When you have depleted your fresh water supply, you will then have full holding tanks. This may take a day or a week, depending upon your usage. You then must go to an appropriate place (dump station or full hookup site) to empty the waste tanks and refill the fresh water tanks.
Hope this helps
