Good input to get this tested as part of your change over. And yes, as you drive you should be maintaining both chassis and house batteries. If your coach has a battery monitor (RC7 Remotes came in many of these rigs.), you can run a test. Leave your coach unplugged overnight with a power draw (maybe leave on several lights). Check the battery level in the AM. Then go out and drive your coach for a few hours. Checking the battery level after this, should see them having obtained more charge. Possibly even fully charged at the end of a two hour drive.
(I only mention the above simple test, as many people don't want to go do at the battery testing. It would at least give you a warm feeling that your house batteries are being maintained as you drive.)
I know that some people who boondock quite a bit and want to conserve battery power demands, sometimes add a smaller draw inverter, dedicated to the fridge. This allows you to turn off the main house inverter when not needed, and would save some battery AH draw. Good quality smaller inverters are not that expensive, so might be worth talking over with the installer to see how much extra it would cost to do so.
Best of luck on your Samsung install!
