Any solutions for high altitude refrigerator issues?

We understand that it is being starved for air and running too rich. From what I have read, there are no other orifaces to get that would work in a Norcold and be a different size. Apparently Dometic has interchangeable orifaces but Norcold doesn't. We might be able to look at tank pressure. Not as concerned with other propane appliances overnight, if we can adjust pressure "-at will" .

Thanks!
