Testing the battery
I have installed a battery that I was concerned with. It seems to be fine. Is there a way to "test" the battery with it installed and using just the trailer's on board equipment?

Basically no. I'd not trust any of the "on board" stuff
YOu can however test it without removal
I use a dual-meter adjustable load tester from Harbor Freight. Not big enough for my big Golf Car batteries but for everythign else it can draw up to around 450 amps and takes only 15 seconds to do the test. (plus hookup and dial up time).
Exactly, forget all this turn one light on, now two, stand on one foot, and scratch your bum. Now look at the green light turn yellow and back to green. OK, switch feet.
Get a battery tester that can load test and be sure. You can also use a volt meter or hydrometer to see the state of charge/discharge. With the a good tester you can also check CA CCA.
