I too would be interested in replacing my Norcold. The lower hinge on the door just broke yesterday. First thing I found out was you cannot just replace the hinge you must replace the door. Then they asked if I wanted the heavy duty upgrade for additional money. WTH - they have known about this for so long they have an upgrade? Just put it on the door at manufacturing or at minimum offer it to people who purchased your early junk for free.
Perhaps this is the best the industry can produce but I do not think so. Surely there is something better than Norcold
