Storage Question Related to Batteries

Going to store our 2015 Greyhawk 31FS for the first time. I can hook up the rig at storage to a regular household plug. Questions for those of you much wiser than I!

I presume with the coach plugged into shore power I should keep the main power disconnect switch on and not isolate the house battery from the charge correct?

Second, do I need a battery tender for the chassis battery or will the system keep it charged while plugged into shore power?

Thanks in advance for your advice!

Ernie

If it is like our 2015 Redhawk, the battery will be charged even if the disconnect is off. The disconnect disconnects loads, not the charging circuit. I know this because we added a digital voltmeter on the wall in the coach so I could watch house battery voltage.

Chassis battery will not stay charged. Battery Tender is a must have. Plug the Battery Tender into a wall socket inside the coach and use the 12VDC power plug on the dash to keep the chassis battery charged.

I store my Greyhawk, plugged into a household type 15A supply, with the battery disconnect off. It keeps the house battery charged. I do not believe it keeps the engine compartment battery charged, but that has not been an issue.

I just hook a tender to the house and chassis batteries. Don't plug the coach in at all.

Reason I plug it in is to keep the fridge on. I think it's best for the fridge to be on long term. Most parts of the RV are made to be used, and don't get used enough!
