The wire between the battery and DC Load Center is 10-AWG. (For DC wiring, TM used this wire size nearly everywhere.) Your "slick car audio breaker" might be the exact one I recommend - "15 gauge and larger", up to about 8-AWG, which works beautifully as a replacement for the failure-prone "spring-loaded cylinder" OEM fuse. There are zillions of EBay sellers, but this one has the highest rating right now, and the best price:

After you've got that in place, you can easily shut off the batteries-to-TM power connection ("+" terminal) while leaving all of your wires in place. (The batteries and TM frame continue to share "-" Ground, but there's no "+" connection, and no circuit). Then, with phantom loads removed, you can use this maintenance device, it can handle up to about 250 AH of 12V battery capacity:

It's a very finicky 8-stage charger. It doesn't work for other battery types, and it doesn't have enough maximum amperage to handle phantom loads and charge batteries at the same time. (It also needs about 2 days to charge a typical pair of batteries from 50% State-Of-Charge.) Here's a picture of mine in action today:
