The house battery usually powers 12-volt lighting, the water pump, and control systems. Standard 120-volt outlets work when the generator is running, the RV is connected to shore power, or an onboard inverter is switched on, if fitted. Air conditioning usually requires the generator or shore power.
Every American RV I encountered on my trip or through Great RV Trip’s partners had a built-in generator drawing from the main fuel tank. You can expect this setup in most of our options, but I still recommend checking the specific vehicle at pickup.
Before leaving the pickup location, find out:- how many generator hours are included and how excess use is charged;
- whether the air conditioner works while parked;
- where the generator exhaust points;
- whether the smoke and carbon monoxide detectors work;
- what noise rules apply in your camp.
If you are driving when a dust storm hits, stop and wait whenever visibility drops to zero. People, bicycles, and structures may be close by even when you cannot see them.
