Monaco Knight M-40DFT - Looking to swap Dometic to Residential Fridge

We currently have a dometic NDA1402 full size fridge in our 08 Monaco Knight M-40DFT and need to replace it. My husband wants to replace with a residential fridge and we are wondering if anyone else has the same RV and has done this? And if so, what model fridge did you go with? What would you change? Our fridge is in the slideout and there is only so many inches left above the current fridge and I am having trouble finding a residential fridge with the same dimensions as our Dometic especially the issue being the height. Our dometic height is 63.19, width is 32.75 and depth is 26.06

Any suggestions? I saw some old posts about a samsung which I'm not too thrilled about (we had a nightmare with a residential samsung fridge a few years ago).

Below is a picture of our current dometic fridge in the slideout. There is not much room on the side where the counter begins and above.

I did this changeover in my previous 2008 Fleetwood Discovery. You might want to try Fisher Pikel (counter depth). It's going to be expensive; but was the best fridge I ever had.

You need to have a Pure Sign Inverter to run the 120v Residential Fridge. Check out your set-up before you head down that road. You may need additional battery support as well depending on your camping habits.

Go to the AJ Madison website, they have a filter by size, just put in your dimensions and it will show what will fit.

The height will be the tough one, unless you have a drawer below or shelf above you could modify.

Width and depth are not going to be a problem. Height is going to be the issue.

You are in the wrong sub forum. Go to the Monaco sub forum and post. You will find lots of information that apply to YOUR unit. These will be Monaco owners who have done the conversion.. Lots of pictures as well.

I had a Samsung RF197 installed in my '09 Monaco Diplomat 40SKQ. The refrigerator in the SKQ floorplan, like the OP's, is installed in the slideout, adjacent to the gas cooktop and microwave.

It was a tight fit, vertically and required some modification to the space below the OEM refrigerator install in order to have enough room. The Samsung worked well with a modified sine wave inverter. However, it was discovered during the install that there was not an inverted circuit behind the OEM refrigerator. The collective wisdom was that the typical OEM refrigerator would have one outlet (for the ice maker) wired to an inverted circuit. That wasn't the case on my coach. That was easily solved by running an extension circuit from the adjacent microwave circuit.

My install was done almost 10 years ago so it'll take a bit of digging to find my documentation.

It was one of the very best modifications that we did to our Monaco.

Take care,

I apologize. The Samsung refrigerator that I had installed in my '09 Diplomat 40SKQ was the RF18, not the RF197 as stated above. IIRC, the RF18 was the follow on model for the RF197. Very similar dimensions for both with some compressor improvement in the RF18.

I did consider a Fisher & Paykel (RF170A series). I know the F & P was significantly more expensive and, I believe that the F & P warranty would be voided unless I upgraded the inverter to pure sine wave. You can check the specific dimensions, but, IIRC, the F & P is inches shorter than the Samsung which would make the installation easier with the height constraint in the slideout.

Here's a .pdf giving some detail regarding my installation: refrigerator install.pdf

The installation was done by Alliance RV in Wildwood, FL. Alliance RV now operates as Lazydays. At the time I had mine done (early 2016), Alliance was doing about 1 a week.

Take care,
