If I leave the rig plugged in to shore power when the unit is stored will the on board charger shut off when the batteries are fully charged or does it keep charging? In other words does the charger act like a battery tender?

Any help will be greatly appreciated.
Hi Kevin. Welcome to the family.

There are many posts & threads on this Forum regarding your question.
Learn to use the SEARCH function and you will find a wealth of info.

1) when in STORE mode, the batteries do not charge, even if plugged into 120v. There is no 12v power available from your house batteries when in the STORE mode .
Note: there is parasitic drain from your radio & CO2 detector. So, if kept in the STORE mode forever, your batteries will drain out. To eliminate battery drain, you need to install a manual disconnect at the house battery terminals
There’s really no reason to drive while in STORE mode. Your coach will drive, but nothing will work in the back.

2) when in USE mode, all 12v works properly. And when plugged into 120v your CONVERTER (on-board Charger) is designed to keep your batteries topped-off, like a battery tender. However, be aware that you need to check house battery water regularly or over-time the CONVERTER has been known to burn up your batteries
