rpod 179 refrigerator replacement

Im looking for information on purchasing another refrigerator that wil fit in the same opening. I currently have a rm8501 which is going to the dump. Never worked correctly ince i bought it in 2017. Also its discontinued so no parts are avaioable. Can someone suggest anew refrigerator dometic or otherwise that would fit thi rpod? Id also be interested in a used newer moel dmetic refrigerator.  thanks

Thanks. Do you know of a electric vapor refrig that would fit? I assume that's a sanford compressor refrig?

I am in the midst of replacing my Dometic RM 8501 as I write.  While it is true they are going to be discontinuing this model Forest River has these in stock as I just had one sent to me yesterday.  When I spoke to the FR rep. I was told last week they had just gotten a shipment of 6 from Dometic.  One was already spoken for so that leaves 4 still available as far as I know.  I was given an option as to getting the Norcold unit which is apparently the new replacement for the discontinuing Dometic.  My neighbor who has sold RV units for years told me to stay away from Norcold as they are cheaply made and have a poor track record on service.  If you are interested in replacing your Dometic with the same model and want more info on who to contact and phone # PM me or let me know on this site.
