Dometic RM 75 cubic feet

Would someone please tell me the cubic feet size of the Dometic RM 75 refrigerator?

I am trying to decide what size I can get away with in my 1973 Tradewind remodel. The opening size is not an issue in my case.

I suspect the RM 75 was less cubic feet then the standard replacement RM 2820 which I believe is about 8 cubic feet

Also generally, I am wondering do you get more cubic feet from the new models than from the old for the same amount of space for the same size unit?


Thanks

Tony

Is your RM 75 non fixable? If it is, I'd refurb it and use it another 40 years. The good thing about the older refers is they don't need 12V. All the important parts are pretty available for the RM 75. They are built to last. I have seen many brand new RV fridges give up after one or two seasons. If you want a really good new unit, I'd recommend a Danfoss type.

A little measuring and you could calculate the ft/3 of the RM 75. I know it will hold 30 cans of beer, half gallon of milk, pound of bacon and a dozen eggs.
I think you probably get more volume from newer units

Ya I am getting the feeling I should of kept it. I dumped it. It probably would of, like you said, last another 40 years. I hate pains in the butt mainly ( I know why do I have a RV) along with my wife saying go new. Oh well. It won't be the last mistake I make during this learning process.

I will check out the Danfoss. Never heard of them

Anyone know the cubic feet?

Thanks Tony

Thanks The prescribed replacement is the Dometic RM 2820 which is 8 cubic feet.

If I go with a 6 cubic foot I gain about 5 inches above it to give a decent shelf area. I suspect the prescribed replacement to the RM 75 has a larger internal capacity in the same foot print. That is why I was after the cubic foot of the RM 75

Thanks for sticking with the question. I don't think the budget will allow for the Vitrifrigo but it could be money well spent.

Tony
