It's not clear when you saw 12.5 vs plugged it in, but if it was charging then the voltage doesn't reflect battery charge state.
Regardles now that it has charged do a load test to determine the battery condition.

When I plugged it in,it was at 12.5V. I have not charged it since sometime last summer, or the fall before. Not bad...

Put them all in use together and see what goes.

12.5 after a week charging is not good. May be marginally OK but not good. Swing by an auto parts store. Most will do a load test for free.
Mixing batteries you get the lowest common denominator so your good battery will be drug down by the marginal battery

He said 12.5 when he "Plugged it in".. Not sure if he mean plugged the battery into the Trailer or the trailer into 120vac
But 12.5 after a long time on the shelf is actually quite good.
12.5 if trailer plugged into 120v is not good.

Agreed, the original post made it sound like he had left it on the charger for a couple weeks.
If it had been sitting on a shelf for an extended period of time not charging, 12.5v isn't bad.
