Update: What I mean is my Tow Vehicles do not currently have power at pin 4. So while towing my TV will not charge the RV battery.

Think y'all misunderstood , or missed this part, or it wasn't there..
But yes it would be a great thing to charge the TT while towing. Always a chance the battery could die, as the refer has to have power to run even on propane. A light could be left on, whatever. Should that happen. The refer will cut off. With the charge pin powered. The TV will power the refer. Depending on your TV. It should be an easy fix to put power to the TT charge pin.
On Fords there is a relay that must be installed to charge the trailer. not real sure about the others. The first thing I would do is find the trailer fuses in the fuse box in the TV, and check them all to see if any are missing, or blown.
