I have looked in a few places but can't find much info on how big of a Fridge or Fridge-Freezer I should be looking at. I have room for as big a unit as is made. But I don't want wasted space either. Use will be for two people on no more than week long trips at this point. I have been using a Pelican 35 quart for food and a bigger igloo cooler for drinks. This has worked well, but I feel the need for a Fridge or Fridge-Freezer combo.
