....Why would you have the battery off if you are plugged in?
to AVOID over charging or BOILING the house batteries dry - ala paralax (non intelligent) trickle charger.
OR when in (long term) storage you may use an EXTERNAL battery charger/maintainer.
I also turn off my ENGINE batteries when camped or stored - just to avoid the an potential parasitic draw (aka clocks etc).

Since the OP was priming with propane I had assumed it was NOT plugged in. Don't even need propane if plugged in.
learned long ago (around here too) that its not safe to assume anything.
while i agree - some have a preference for running their fridge on propane (could be a way of reducing the load on a marginal shore power 120vac supply circuit.
when curbside at my father-in-laws i run my water heater on propane because i can not run an air conditioner, fridge & water heater on his 20a shore circuit - sometimes if my 120vac load is "close" to the limit i'll run the fridge in propane/12vdc mode to avoid the consumption of the 3+ amps that the fridge can consume (on 120vac).
