Steve, A relay from a set of driving lights rated at 40 amps is sufficient for this job (under $15). An isolator is not necessary and wastes energy (hence the cooling fins). To be on the safe side, add your own wire (6 gauge) for the charging circuit. Leave the existing fridge wire and relay because you do not want to discharge either battery with the power hungry fridge. Change over all the rest of the camping wires to the aux battery (fusing each of course). An easy way to put the cabin lights and radio and cig lighter on to the aux battery is to remove fuse number 3 and run a wire from the aux battery to the fuse connector.
