Stock SMB wiring is to connect the house batteries EVERY TIME YOU TURN THE KEY.
It hides starter battery problems until you cannot start at all. Remove the green wire to fix... at least it was green in my build.
Tracy, I'd have your alternator tested. In the 15 minutes I drove with a bad alternator and new batteries I had a bunch of corrosive "growth", more than I'd ever seen (although mine didn't destroy the battery). My van has been eating starter batteries and I've always had problems with the house side as well- pretty sure my alternator was overcharging the whole time I've owned the van, and only recently did it stop putting out the volts which alerted me to the problem.
