Silver, nice run through of your protocol. It's obvious you have thought about this a lot. Once we
1. added 200W of Solar
2. replaced the kaput converter with one with a charge wizard
3. replaced all the interior bulbs with L.E.D.'s
4. put an aluminum flashing wind shield behind the front half of the fridge vent
we could stop using the fridge on 12v while traveling (the fridge would not stay on prop while moving @ more than 50 mph) and stop using our battery operated lantern at night in the box. We don't use any appliances that suck power like a microwave or Keurig.
On the last couple trips there were zero worries about power consumption.
We have all three, same size group 27, 12v batteries ganged together (with a cut off if we need it) using the two truck batteries and the one in the TC. The only way our set up could go south is if we were camping in a tunnel.
Everyone develops their own power system and renewal. I'm always awed by the lengths that some of the electrical gurus on here go to make it work.
