OH - one other thing you might try to check -- with the battery slightly discharged on the TT - leave the car off and plug in the 7 pin. See if the voltage goes up slightly. If not, turn the key to on, but dont start it and check the voltage again.
On some TVs - like my Chevy - the 7 pin is hot all the time. If I were to leave the TT plugged in for a long period of time you risk of draining your TV.
On the plus side, if I keep my 7 plugged in at the camp site it tops off my TV battery
