OK, this is what ive come up with. run 4awg from battery to rear of patrol to anderson plug. then 6awg from anderson plug to the two 95 anp/h batteries.( in parallel) from 2x95 amp/h batteries to fridge using more 6awg auto wire
I will use a 30 anp breaker at each end.

Slush you probably should fit a battery isolator in the car to avoid flattening the start battery if the van is left connected. I would use no smaller than 16mm squared cable (not sure how that relates to awg) from the car right through to the van batteries to minimise voltage drop with a 6mm cable to the fridge through a 20amp blade fuse. Depending on the type of battery isolator a 30amp CB should be big enough.

One problem I can see is the 30A breaker, those 2 X 95A batteries will pull far more than 30A when flat, probably at least 60A for both. I'd use at least 100A breaker between main battery and the 2 X 95A ones. And if you run 4awg to the plug why not 4awg to the battery no point in dropping to 6awg. Use 6awg to the fridge if you like.
