Nania,

Our model is an older 45 something or other ,now discontinued, but most parts still available.
The fridge in the Montana is probably 8 cubic feet, or at the very most 10 c. ft. We tend to buy a lot of produce and freezer items ahead and take with us on a road trip, so having the extra cool storage and/or freezer space really helps this approach.
By the way, our model is one that has only one moving part, which is pretty amazing, and no doubt a factor in its longevity.
