Going with a residential fridge mod works well for many. Another option is the change over to the Amish Cooling Unit. Costs with 25% of each other if paying shops to do the work. If doing the work yourself, could be pretty equal.
Much depends on how you use your coach, if you are mostly 'Park to Park' with full hook ups, residential fridge is a good option. If you are a heavy boondocker, then retaining LP does provide a nice option.
The Pro's of he residential fridge is more space for food, usually with the loss of a few drawers of storage. (Depending upon coach.) The Pro's of Amish Cooling unit, is the LP feature provides options for boondocking, and also for in case of emergency where power outages may be prolong. (Hurricanes, earthquakes, etc.).
No right or wrong on this, as it is a matter of choice and how you use your coach.
I will say that the Norcold 1200 unit is not the greatest fridge. I see it as being dangerous in OEM build condition. But, the Amish Cooling Unit, and say the addition of the SS-30 Halon extinguisher within the fridge cabinet, I feel provides a very safe refrigerator.
I did the Amish Cooling Unit, instead of the Mickey Mouse recall Norcold route. I have the SS-30, and I also added extra cooling fans to augment in extreme heat conditions. For me, it would have been less expensive to go the Samsung route. But, I wanted to retain LP capability. Today? Not as important to me, as I've added an 800AH Lifeline battery bank, and 1200W 48V Solar Panel system. If making this decision today, I'd face the wrath of the DW losing her two lower drawers, and go the Samsung route
But, you have options to consider
Best of luck,
