I guess the "weekend" campers differ somewhat from my RVing. We could've had a choice of 3 different Frigs in our TT but opted for the smallest of the 3. We tend to eat fresh food so the food is cycled through our frig daily. Secondly we are on the road for many months of the year and didn't want to give up cabinet space for our specialty foods that didn't require a frig. Thirdly, The park we stay at in the winter months offers free ice, all you want any time day of night. Lastly there are foods like soups, lamp stew, and many others that we store in freezer bags and stack them like cards in our freezer along side of a frozen thanksgiving turkey dinner to a lot of Polish goodies no available out west or in much of the south. When we leave home you couldn't put a pea in the space left over.
Do your own thing but a large frig for us is a home not in our trailer.
