Sorry Bill' I missed your question. First I replaced the original Nor cold about 6 years ago with the Dometic( not extremely happy with 6 years of limited and very gentle service seeing I didn't want to spend another 1200-1500 for a replacement). My dimensions are as follows: w 23 11/16 d 27 1/2. H 59 11/16. With that being said, I do have very little wiggle room. The depth is the least of the worries...I don't mind if it sticks out in the front a bit. Height and width are a totally different story. Above the fridge now is a main 12 volt distribution center below..may have some room. Width wise...its wedged in between the pantry and the dinette..maybe an inch of room if I'm lucky and that would result in little to no clearance for the sides. Hope that helps...I'll check that Samsung unit out now...thanks.
