Jason-
I won’t say much bad stuff about residential units, except that my personal experience with Samsung-built ones and Samsung-made components of other products has put me off the company. Obviously others here have had little such experiences. We have Samsung Android phones and “wireless” chargers, with no issues except one charger that occasionally overheats.
That out of the way, I’ve had few problems with Dometic RV fridges on our motorhomes. And practically all the problems I read about any RV units involve Norcolds. Breakdowns of my Dometics were of my own greenhorn neglectfulness, not quality of product. 35+ years ago the addition of a solar/12v fan to the rear of our old coach’s 8c.ft. made a big difference in its cooling ability in hot weather. Offering afternoon tree or hand-made shade of some sort over the fridge outer wall and door can help.
Our current 14cf Dometic did pretty darned good parked a month in midsummer eastern Nebraska heat in 2012; most days were 90-100 degrees and too many exceeded 112F with humidity this Willamette Valley native wasn’t used to. Yeah, interior fridge temps then pushed 50+ mid-day and I opened the outside door on occasion to help ventilation, or moved some cubes from freezer compartment to fridge. I flirted with installing a rear compartment fan setup at the time, but encountering such ambient conditions is too rare for us. Normal ambient temps/humidity aren’t a challenge for it.
So I guess you can tell I’d have to encounter repeated, confounding breakdowns to entice my changing to residential, and it would take some convincing to make it a Samsung or any brand built by them. That’s my personal opinion based on experience. That doesn’t mean I’m encouraging you to dismiss that of all the others here who like their residential units; you can’t ignore the many good reviews and installer recommendations. I just would hope, for those that elect to switch, that there were other non-Samsung made brands to choose from.
Probably your wife’s biggest concern if you’re full-time is the size of the fridge. Regardless of what you do, that’s going to take enlargement of the compartment area, which is likely where the most engineering and work will be.
