I installed two Samsungs, one in my previous coach and one in my sister's coach. The model that was a perfect fit was discontinued, but the newer version still works, it's just a tad larger. Haier also makes some nice refers.
(Personal Opinion) If you put the cheap two door refers in, like the old style freezer on top, they look cheap and cheapen the look of the motor home. I know some can only fit this type in, but just something to be aware of. The French door units really look nice. If you have to go with a two door, get an SS model, to make it look nice.
I sold my Norcold on Craigslist for $300.00. The buyer was going to use it in a cabin. My sister sold hers for $350.00
