Curtis,
Your univolt will be on when you start the generator. You may have a switch to turn it on and off, many do. If you have a regular household light switch that does not seem connected to any thing that is normally the univolt. If you cannot find the switch you may have an AC breaker on you AC panel that performs the same function. Battery chargers/maintainers use only the peak output from the 60 cycle power provided. So if you are running your AC and other appliances on the generator you may want to reference a plug in AC voltmeter. If your AC output is in the 110 Volt range on generator, your univolt will not do much in the way of charging. If you are happily motoring down the road your alternator should be charging both the engine battery as well as the house battery/s.
Enjoy your trip, getting there is an adventure to be savored.
