Need help Norcold 1200 with a Amish cooling unit

Lets see...you have to take your windshield out in order to get the home type frig in the coach right ?.......ehh no I'm not going there. Thank you very much..
Our 18 yr old Norcold 1200 is serving us very well to this day..Its just as efficient as our home refer.when it goes I'll get it fixed or buy one that fits through the door..Taking your coach apart to fit the home type refer in is sheer insanity.Now if they have one that fits through the door of course thats a different story..
