In my opinion the 8 series fridges are not adequate. The 2 door 8555 is better than the 1 door 8555 or the 8551, but still not good enough. All the extra insulation, fans, grills, etc help a bit but do not solve the problem.

If you are willing to use a cooler and/or not camp in temperatures above 90 then you may be satisified with an 8 series.
Hi: jamman... Since we couldn't attend the ETI Rally last weekend we camped locally. Kept a cooler full of "Barley sandwiches" and other beverages, and tried to stay out of the RML8551. It was on the sunny side of the trailer all weekend with temps in the low 80's. It performed to specs with rising temps at meal times and cooling down over night set on 4 bars. Mods I've done are move the thermister to below the cooling fins and plug the hole in the bottom of the door.
Now the abundance of fish flies was another matter. We went out Sat. am. and caught a pound of yellow perch and a pound of white perch. Pan fried on the hot plate at the table. YUMMM!!! Alf

Although it may be cooler inside the trailer with a/c, the refer is "outside" in the heat, trying to cool things. I'm sure if you put your house refer out in the yard in the midday sun you will see a difference than normal.

Golly, get a new kitchen and you are reduced to pan frying on a hot plate
Afraid of getting the new one wet?

Dometic RM8551 insuffucent cooling

The fact that the fridge has an SN rating does not mean it won't cool adequately in most situations. Our 2 door RMD 8555 is also an SN rated fridge, and works fine. Just don't expect it to cool as well as an N rated or ST rated fridge (or equivalent) when it's above 90 outside.

I know this has been beat to death over and over but for what its worth we camped in 90+ degree weather this past weekend and I was able to keep the our RM8551 below 40 degrees even when traveling. At some points the outside temp hit 96 Friday while traveling.

As I have mentioned before I have made several mods to our fridge and the fridge compartment and did have the freezer compartment removed (which you cannot do with the Americana) to give added cooling to the fridge but was actually surprised with its performance in this kind of weather. I ran the cooling fan outside during the day and would drop the fridge temp down to 34 at night to help the next day.

One big thing while traveling is to make sure water is added to the drain cup outside so the air can not go up the drain tube and back into to fridge while traveling. When we left to come home I forgot to add water and the temp raised a couple degrees in the first 10 miles. I pulled over and added water to the drain cup and the temp held for the 4 hours we drove home and actually dropped 1 degree as we got close to home. I used propane going and 12 volt on our return trip.

I do carry a cooler and would use it for drinks so we could reduce the number of times the fridge was opened during the day.

In this kind of weather our Americana fridge in our Casita struggled too and that should be expected.

Tom , we had just about the same numbers with temp going up outside into the 100's , 102,103 ,last long trip . And we dropped down to 31 , I couldn't believe it . Same fridge after mods, some with your help . Didn't know you can't remove the freezer compartment on Americana . Liking my series 8 more and more . Didn't know about the water in cup either . We also if just by habit bring cooler . If for any reason your frig isn't working you have cooler for your food . Pat

There is a condensate cup on the back where water and ice that melts upon unplugging drain into. It connects to the interior drain via a clear tube. On some models people drained this water right thru the vent outside or thru an overflow in the refer compartment. But it seems that warm air can enter the refer compartment while traveling if the tube is exposed to air vs water. thus the need to make sure the cup always has some liquid. Another way to to form a "J" trap similar to your sink drain in the drain tube to keep water in the line and air out. After sitting for awhile this too will evaporate.

Jim when I was in the back saw that little cup with water in it but didn't understand you want the water in there . I knew it was coming from frig that was draining there . Just didn't realize it's importance in helping with fridge temps . Makes sense though . Pat
