I believe motor home battery charging is prioritized such that the chassis battery will get charged first, then switches over to the house batteries. If your chassis battery needs to be charged, then you will get the measurements you are seeing.
If you have a battery charger, I would charge the chassis battery that way to assure it is fully charged. Then start and idle the engine for a few minutes, then measure again. You are trying to get the electrical system to switch over to the house batteries. If you can't make it happen, then with the engine running, hook up your battery charger to the chassis battery and measure again.
