I installed a Samsung 17.5 December 2017. The reviews on it were terrible but I took the chance with it because it was the only model that would fit the width of the existing Norcold 1210.. I did lower the floor by removing the drawer and installed a strap system to the floor. Lowes delivered and installed it, the ice maker never did work and on the fourth day the freezer had quit working. With Lowes you can do a return within 30 days so I ordered a Whirlpool WRS571CIDMO2 20.6 Cu-Ft and then I had to widen the width of the cabinet I believe to 37 inches and lower the floor again. I solved the water supply issue by running the ice maker supply line out the lower rear vent and tapping in the water hose with a brass hose Y and hose thread to 1/4 ice maker adapter. I used sheet foam from Home Depot to seal the upper rear vent. Their was no room left for a strap system to hold the refrigerator in place so I went to Walmart and bought two play ground rubber balls, deflated them and put them on top of the refrigerator and re-inflated them. When we moved the trailer a few months later 170 miles the refrigerator never moved at all. I bought trim molding and stained it, there was a two inches gap on top so I bought garage door rubber strip seal and stapled it the the inside of the molding. Four months have gone by and so far no problems.
