As the OP asked about the ability boondock with a residential fridge, to validate what the salesman said, I answered in that direction.
As more was appropriately mentioned about the danger of the Norcold 1200 series, I'll toss in another $.02.
I'll condition this by stating that we are probably going to shift over to a residential fridge at the first of the year. Not because because we are having any problems with our modified Norcold 1200 (See below) but because we want more space for cold and freezer storage.
IMO, do not trust the mickey mouse series of recalls from Norcold, their one band aid after another, and none of the handle the root cause - inferior and or contaminated tubing used on the cooling coil. Even with recalls done, I believe the risk of the Norcold stock cooing coil is too great to take.
Before we added our Solar Panel and larger bank of Lifelines (1200W of 48V panels feeding 800AH's of house batteries), we went ahead and made the following modifications of the Norcold 1200 to support longer off grid boondocking:
>Amish Cooling Unit
>Added switched controlled additional pancake fans. I turn them on when in high heat of humidity conditions, and the fridge is working harder.
>SS30 Halon Extinguisher
>Smoke Detector behind fridge
If we end up not doing the residential fridge route, I'll also add the ARB board.
Again IMO, the Amish Cooling Unit and ARB control board, provide a very safe running propane or electric refrigerator.
I highly recommend anyone wishing to retain the Norcold 1200 series, due their own research. The modifications to make it safe are not inexpensive - but how much is yours, or a pet, life's worth?
End of my $.02.
And OP, the Intrigue is a fine coach. If not that one, keep on looking. Hard to go wrong with a good well maintained CC
Best to all,
