Best decision you can make. We have had both a Dontgetcoldmetic and most recently a NoCold in our current RV. I pulled the Nocold out and replaced it with a Haier purchased at Lowes that fit perfectly in the old fridge spot. We were not looking for a fridge with all the bells and whistles just one that keeps your food cold and has a freezer where ice cream actually stays cold.
The hardest part of tearing out the Nocold since it was firmly in place with glue and foam. New fridge came through the door with the fridge doors taken off easy peasy
Saved myself a pile of money doing it myself rather than having a dealership do it. Just remember, measure once, twice, and then measure again to make sure.
