Anywho, I don't have nearly the capacity you have, just a 125ah deep cycle and I don't really "charge " from the TV just maintain battery and power reefer while driving. I just put in a relay to isolate TV from trailer when parked. I did run 4ga from TV to trailer and I have a 225a alternator, but I can't remember what the voltage was at trailer battery when charging from TV. I do know that I always arrive with a full battery and cold Jameson, so there is that....
Looks like we may have mild winter and a early spring here. (I wish) currently 22f and headed for 49f this afternoon! I've got a ton of things to do, but I'll probably just sit in a lawn chair with a cigar and some "vitamin water" and enjoy the day.
If you run into Richard tell him we are thinking about selling the ranch and filling the trailer up with cash and heading towards Frostproof... It may take us a while. We'll call you when we get to the Big Easy.

Please post pictures of your method for bringing power from the TV to the CT conversion. Besides general interest, I'm curious as to what connectors you'll use and where the tie-in will be to the 12v side of your electrical system.
Thank you and take care,
Tom

Below is an excerpt from the manual:
“Installation of a Diode to Suppress Voltage Spikes.
When an electromechanical solenoid or relay is de-energized rapidly by a mechanical switch or semiconductor, the collapsing magnetic field produces a substantial transient voltage in its effort to disperse the stored energy and oppose the sudden change in current flow. These voltage spikes can occur at the positive terminal when the solenoid or relay is de-energized (keyed-off). If a solenoid or relay is wired onto the Run/Crank circuit of the vehicle to control aftermarket equipment, the spikes can be transmitted onto the circuit. The spikes can permanently damage the internal circuitry of the sensitive electronic components and/or control modules that are on this bussed circuit. To prevent damage to these components, the solenoid or relay MUST have the control circuit suppressed with a diode.”
The diode called for in the manual was a 1N5404GP diode which I bought from Radio Shack.
