Thank everyone for great comments!
My motorhome is indeed a 32N. It has been on Shore Power, for over a week, with the Use/Store switch on Use. The house battery is at 13.18 volts.
Although 13.18 is a little high for just maintaince(sp), I think it is OK to leave it, as is, while storing, but check battery water every month.
Toggle the switch to Store and use a BatteryTender on the house batteries and one on the engine battery for prolonged storage.
