Beginning to like the idea of making that fan in back do more work.
Wow Myron, 107 out and your frig is 44, that's pretty dang good! When we had a smaller refrigerator we would have been very happy with that. We usually would throw a bag of ice in until we moved on to cooler climes.

I'm not so sure that 107 degree reading is a fair one, though. The remote sensor is inside my tongue box. The box lid was open but full sun was shining at it. Yet, what I reported is what it was. Testing continues through today. Teaser: this morning at 7:45 AM--fridge temp was 31 f. Last night it did cool down outside quite a lot.

More to your point though, I know of no 3 way fridge with a similar capacity that is less than 22" wide and can fit through the door. In order for Escape to go to a different manufacturer or model, that's a redesign of the trailer shell - and the door in particular. I think Reace would love nothing better than to have a fridge that performs well in the 90s and 100s. As to why Dometic won't sell a tropical rated version of this fridge in North America (they do make one - like this one for example: RM8501, 106LT FRIDGE, LH | Dometic Australia) I have no idea, and they won't say.
Re read post #110 . The 2 previous Dometic I had didn't have these huge clearance's all around .Dometic recommends 0-1 in all around . Don't know about yours but the cavity back there is way over that . The walls of these new frigs are not as insulated or thick as someone posted earlier mentioned Insulation is very important . It is interesting if you have the new and improved 6.7 you are happy . Good for you . You are not experiencing what we are. I changed out my heating element in both my previous Dometic's and also removed them for other reason's . One in a 1979 class C , one in a 1992 camper . I owned both for 12-13 years each and was 2nd owners with both so they were old hence needed a little 40. repair . You don't think we know what we are experiencing ? As Jubal said maybe not sell this 4.3 unit anymore unless you know what you are in for . I have said before even though I didn't want or need a huge frig if I knew what I know now would of gotten the 6.7 instead for 200 more . I am getting close to spending that now anyway . Pat

Speaking of taking a cooler, I wonder what the temp in those things are when sitting in 90F weather (but I don't care enough to find out). I'm also wondering if in the old days, the RV refers were all that good. I never even thought about measuring the temp inside mine until all this came up for discussion. Now we have the remote sensors that maybe tell us more than we ever knew in the past. Just pondering here...

Speaking of older models. Couple days ago thermometer registered 90.1 F inside the trailer and 42 F in the 5.0 cu. ft. fridge set on 5. But, the fridge hadn't been opened for a couple days.
I expect if I had grabbed a beer, the fridge temp would have risen four degrees and taken some time to cool down again.

I have thought the same thing several times about having the thermometers with remote sensors. Maybe we have too much information and things have not changed that much.

Reace mentioned once that he talked with Norcold and they would not guarantee any better performance.

Sarcasm never solves problems. Life is short, take a cooler and spend more time camping and less time complaining.
Hi: Kountrykamper... "Take a cooler". Would that be Seagrams or Mikes? Alf

A few weeks ago, I bought a pretty pricey ($240US) 35qt Canyon Cooler. Has a neoprene gasket on the lid, two latches, and is made of kayak material. I put 18 cold cans of beer in it with along with two bags of grocery store ice. Came home after 5 days with three cans of beer and a bunch of ice. It was a fun experiment. Conclusion: anything that needs to be REAL cold should be in the ice chest. Anything that needs to be preserved and fresh goes in our 4.3.

Ahead of you Rich bought a Penquin cooler a year ago a little cheaper but made real well . After done with this fixing need to drag along . In the 19 , 2 people and 3 dogs got to find a place . Don't want to have to go out to truck every time . That was the purpose for better table lift . Can stick cooler on passenger bench and still sit at table . In winter the smaller cooler works ok . Fits right under fridge . Summer is the problem . Pat
