I was reading through the thread because I found out I could get a 350a alternator for the Expy and the info may come in handy someday.
What I can add is that I have been looking to add the second fridge next year for extended trips and am going through the same process that I did with the little A/C. I have found that most 1 ft cube fridges pull the same 1.3-1.5a as the larger 2 and 3 foot units. oddly you can find 10 ft units that use little more even though they are 10x the space.
The least draw I have found has been the Edgestar 3.1 two door. It pulls .64a which is only .04a more than a Grape 5 ft 12v fridge. Adding insulation can drop the daily draw down 40%.
Jim,
You have found the holy nugget of wisdom about refrigeration, the smaller ones have almost identical draw as the big ones. As the boxes get bigger, they have more freezer space and different air transfer designs within the box. This can add to electrical draw. My 1.8 cu ft. refer draws 80W. The duty cycle in temperate MN Summer is 1/3-> 1/4.
