My RV is parked on a gravel pad next to our house and is plugged into a 30 amp socket to allow the television to be powered on all winter and keep the converter charging the battery. I can see it from...

Any sort of light left on would only make the problem worse. If your converter was charging your battery your light would be on. When the converter stopped for whatever reason the light would still be on but now battery powered. It would drain the battery down and finally go out. You would then know your battery was dead but that isn't much help.
In order to monitor the battery you would need to use Jim's idea of extending the leads on a voltmeter. There wouldn't be any voltage drop because there's no load so no need to worry about that.
Here's my idea: turn off the TV, I'm not sure why you want it on anyway. Disconnect the battery and bring it inside. Put it on a trickle charger somewhere that you can see it regularly.
Or, even simpler, don't bother with the trickle charger. I take my boat batteries out in the fall and let them sit in the garage all winter. In the spring I reinstall and they start the boat fine. The last set of batteries lasted 7 years like this.
