When you set up duel batteries in the tow vehicle through the Redarc isolation switch ,do you run your wires for the fridge freezer in the back ,off the crank battery or the auxiliary battery or doesn't it matter,and also do you need to put a fuse or circuit breaker on each pos battery lead to the isolation switch, many thanks.ps if I need circuit breakers what AMP and what AMP fuse if needed.

You need a fuse at BOTH batteries as any short to earth in the connecting cable can draw from both. We use 100 Amp fuses as the same cable also runs the van fridge (3 way ) and a DC_DC charger for van battery when required. Total current can be very high on occasions.
I also assume the reason for the auxiliary battery is to run the fridge in the tug so wire it only to the auxilary.
