Trying to figure of Inverter/Converter, etc.

No, it's aftermarket. When I negotiated a below MSRP "Out-the-door" deal both the salesman and I were exhausted from the ordeal. He wanted to really make back the lost profit on any options, which I decided were WAY too expensive to get from Honda. Camping World installed the Prodigy Brake Controller and the charge line. The blocking diodes are supposed to allow me to leave the trailer plugged in with the engine off without draining the car's battery.

Yep, that's what I thought. I believe factory-installed tow packages accommodate for the possible drain on the TV's battery by a trailer so ancillary blocking diodes are not necessary...

One minor point when using blocking diodes to protect the tow vehicle's battery - a diode drops close to 3/4 of a volt. This, combined with the size of your power cable may reduce the voltage from the alternator to the point where little or no charging takes place in your trailer. Another solution is to use a solenoid. Be sure is is one designed for constant duty - starter solenoids won't hold up. Check RV Battery Isolation Relays for more information.
