Stay away from Samsung. OEM's have dropped Samsung because finding a Service Center that will work on Samsung refers IN RV's is difficult to find. I live in the DFW Texas area(VERY large area) and we cannot get any Samsung Authorized Service people to come work on Samsung in RV's. Not a problem if you expect to have NO problems under the Samsun warranty, but a big problem if it does malfunction. Remember, you disassemble both the Dometic interior doors and door brackets to remove the refer. You do the same to the Residential when installing it, so it does free up some space. Just make sure you do NOT have a curved roof in the refer cabinet where the interior roof meets the sidewall. The top of the Residential will probably hit that curved spot and you cannot get it in that last 1 to 2 inches. The last one I had that did that, I had enough space to notch out that part of the interior roof to get the refer all the way in. Doug
