You'll want to charge those 6V's with as much as you can muster. Stopping at 12.7 is only about 3/4 charged. If your solar charge controller has adjustable output, set it at 14.8V for initial charge and 13.6V for float.
I'd also suggest to trace the wires in the trailer's umbilical cord to see that the charge line from the truck is connected to the batteries.
Another suggestion: Stop at a home improvement store or Harbor Freight and buy another meter. Keep that one in the trailer. Without a meter, you're relying on idiot lights or hearsay from someone else. You need to know how your batteries are being/not being charged.
