Thanks for your replies! Forgive my ignorance, the camper is in storage right now so I can't look at it. Is there an easy way to tell if it's 6 or 12 volt?
I have two batteries on the front tongue behind the propane tanks. One in the factory tray, the other perpendicular to it off to one side. I'd like to put a tray parallel to the front of the camper that will hold both batteries. See pic.
