Dometic RM3862 Residential Replacement?

I'm trying to help a friend find a residential replacement fridge for her Dometic RM3862. But so far haven't come up with anything that would seem to work.

The problem is the size. The RM3862 is 59-15/16" H, 23-11/16" W and 24" deep.

Has anyone replaced one of these, or know of a replacement?

Thanks.
