I had an original Dometic 211 3 way fridge
into my Trillium
1977 that was in poor condition. The interior shell was broken in several places, the door seal was shut and the cooling system in questionnable condition. Looking for replacement unit made me aware of the following problems:
1- The only replacement units available are 3 inches deeper than the Dometic 211. Original unit is 19" deep, all replacement units need a 21" deep space to fit. The Trillium
curved shell does not allow anything deeper than 19" and installing newer units protruding 3" from the cabinet would be very ugly and not practical.
2- The Norcold fridge
gas line is on the right side, the Dometics on the left side. I found a used Norcold 323 in excellent condition, so I had to change the gas line side.
3- The potential replacement units are 1.5" narrower than the old unit
1- I did cut the outside fiberglass shell, installed a board shelf protruding 2" outside and rebuilt a shell to hold the original bottom vent out of aluminum.
2- I installed a wood frame inside the interior cabinet opening to make it level and 1 1/2" narrower on all sides and protruding only 1" indoor.
3- I cancelled the old gas line and routed it on the right side
4- I adapted the funnel shape fiberglass ventilation insulator, so heat is routed completely outside.
All I can say, it fits and it works just fine. Most people would think it is original, except when they open the fridge
I prefer the Norcold unit because temperature is automatically regulated under 110V or 12V, as opposed to the Dometic 2193 which is the only other option that is now available in that small size.
