However, we will be traveling a fair amount between campsites so the TV should help with charging some as well.

You won't like my answer, but the truth is you will need at least 3 battery chargers NOT including the charger in your converter.

First, for fast, but not necessarily complete/perfect charging get a "generic" 12VDC power supply capable of more than 100A. Make sure it can be adjusted to at least 14.5V. You must run it off of a timer because if accidentally left on too long, it will ruin your battery.

Second, to charge your house bank will driving, get a DC-DC charger, like a CTEK D250S or similar. After a short bulk charge with the first charger, this will finish the job.

Third, get a multi-stage charger for use when you are on shore power (or at home). This will take several hours but it will make sure the battery is properly charged before your next trip.

As long as I can run a few lights and the AC if needed then I think we will be good.

You are NOT going to be running an AC for more than a few minutes with only two GC2 batteries. Even four GC2 batteries will not get you up to 1 hour of run time.
