Next, your 40 amp CB with NOT limit the current from going from your battery in the box, to the starter motor when you start.

There is a complex science surrounding how automotive fuses and CBs work, and you 40 amp CB could easily tolerate a current draw well over 100 amps, for a second or two, before it trips.

This high current draw will not occur, because of the size and length of cabling running between your battery box and the front batteries.

So you do not need to be concerned about such high current draws because they will be safely handled and CONTROLLED by your existing setup.
Cheers, thank you!
Enjoy your holiday.
I will now, knowing my battery's safe and the beer will remain cold.
