thank you for the response, javelin. i still have to reread this a few times LOL but what i think i understand your point about the house batteries being so dead now that being plugged into shore power (even if just 115) the use/store button is stuck in store - so even though i am plugged in - the house batteries can't get charged. wondering - could i use a regular car jumper cable from the new truck battery to one of the house batteries to charge it for a bit to get it so the use/store switch will work? and if so - what configuration of red/black on each end should i use - red black on the truck battery and red/black on one of the house batteries? and - an aside - should i bother with the 12V battery tender on the new truck battery - or should i disconnect the positive instead - (for when the truck is just sitting in the driveway? thank you!!!!!
