You WILL want at least 200 Ahr battery capacity to run the residential fridge overnight and while traveling. Gives you enough battery to handle some lights, heat and perhaps water pump while overnighting with some capacity leftover for the next day.
For my setup, I am using a pair of 6V GC batteries with 210 Ahr capacity. This allows me to drive 8hrs the first day, overnight without power for 8-9hrs then drive another 8hrs while running the furnace overnight and a few lights for a couple of hrs..
Don't depend on the Tow Vehicle charge line to provide much recharge power, that connection might yield 5A-10A of charging unless you majorly beef up the wiring on the tow vehicle..
As far as precooling the fridge, as others mentioned, not needed, residential fridges cool down extremely fast. Mine is at proper cooling temp in 20 minutes which is amazingly about the same as a normal cooling cycle.. Might even be quicker if you have already loaded the fridge/freezer with already cold items.
