Len, the above is technically correct. To state it a bit differently,
When traveling down the road your engine alternator will keep the battery bank charged. If you have your inverter turned on you will be able to power your residential refer. By doing this you do not need to run your generator just for the refer. If however you are also running the A/C, run your genny, the inverter goes into bypass and does not use the batteries.
As stated in a prior post, many people, myself included, leave their inverters turned on all the time. If you are plugged in to shore power, or running the genny, the inverter goes into bypass mode and passes shore power directly to connected devices, thus not using the battery bank. The main reason to do this is to protect those devices connected to the inverter from a power failure (your refer will stay cold when shore power or the genny goes off).
