connecting "in-series" batteries
My travel trailer's batteries were stolen and now that I have 2 new ones to reconnect them, but of course they were already properly connected when I bought the trailer and I never had a need to mess ...

What year and make of trailer?
What batteries? I am assuming 6v since you are connecting them in series? WIth two 6's you make a 12v battery by wiring the + on one to the - on the other. The unused posts become the + and - of a 12 V battery. But this of course is NOT the way to hook up a pair of 12v batteries if that is what you have.
As was mentioned, people have done significant damage reversing polarity, or connecting to 12v's in series and putting 24V to an RV system. Proceed carefully.
The ground wire(s) should show very low resistance to bare metal on the Rv chassis (with nothing powered up ideally).
If it is a newer rig with the right kind of converter (what model do you have?) you can power up the converter without a battery connected (not with any disconnected wires where they can short to anything!) and the wire to it will show up at 13.x v most likely, relative to ground. That one goes to the + when hooking to a single 12v battery.
