Norcold 1210 replac

[MJD]

My Norcold 1210 is working perfectly but i have just watched 2 neighbors spending over 3000$ fixing there broken one. I was converting my montana to a inverter ac operation . I see the replacement new is over 4000$ an insane amount for this fridge.
Anyhow i see all sorts of on line info on replacement to an AC fridge but looking for anyone whos done this to a Montana and specifically to the modification required to re fit .
