When you say "use the lights", do you mean the inside lights in your trailer? Or the actual running and brake lights of the trailer?

Well I bought a new battery in July, and I tested it this weekend and it's dead (like 0.175 volts dead). I have outside lights like turn/brake signals. But absolutely nothing inside. So I figured that when the trailer is plugged into the truck I should be able to get something there? Even after a couple hour drive though, nothing at all.
When I was at a fully serviced site I had no issues, so I know the issue is in the DC line somewhere... and theoretically not the battery. I should mention that when I bought the battery I camped with it the same weekend and had power for the lights and water pump that weekend.
