Welcome to IRV2! We're sure glad you joined the gang!
Depends on how you're gonna recharge them! As 007 said, if you can hook to shore power to recharge them you will need the battery disconnect switch on. If you use a portable charger I think you would want the switch off. JMHO!
Good luck, happy trails, and God bless!
