I am thinking I will go with a new charger similar to the battery tender. Any idea what amp I need or better yet a particular one. I only have twobhouse batteries and of course the one that starts the motorhome engine.

1000ma (one amp) per 100 amp hour 20/hr rate battery is enough capacity for a float charger. So 2.5 amperes float capacity is a good safety margin.
The batteries must be 100% fully charged verified via specific gravity before the float charger is enabled.
The batteries must be physically disconnected (electrically) from any possibility of having a ghost load overwhelm the float charger
