Just returned from a 9,000 mile trip around the US. Thought I'd let you know how the RMD8555 performed. We had it swapped out at Escape the end of July. We were traveling mainly in August and September. The fridge worked fantastic on electric no matter what the weather. Even when the temps were in the 90's we had no problems keeping fridge in the 30's and the freezer always kept everything frozen.
Here's the glitch: we would switch to gas in the morning and by noon, the fridge was up to 42 or 43. One day I forget to check and the temp had climbed to 47! I threw out the perishables. We bought a small ice chest and around 10 or 11 we would put some bags of ice on the shelves and one by the milk. We would take them out once we had electric and the the temps would drop back to the 30's within an hour.
One fellow who moderates several RV sites posted this regarding poor cooling with gas:
"The "coolant" goes to the freezer first, then the refrigerator, so compromised cooling capacity affects the refrigerator first.
Start by making sure cooling capacity is maximized:
1. Defrost if more than 1/4" of ice.
2. Do the "dollar bill test" to verify that the door seals are snug.
3. Insure that the restrictor is in the bottom/outside end of the condensate drain.
4. Check that air flow in the bottom and out the top of the outside refrigerator area is unobstructed.
5. Particularly if the upper refrigerator outside vent is in the side vs roof, make sure there is no "dead space" above the refrigerator that can accumulate heat.
6. Do the burner area tune-up as outlined in your Dometic manual. Even a slight decrease in flame size can have a detrimental affect on cooling performance.
7. Lastly, use a manometer to verify propane pressure."
So what do you all think? Why isn't the fridge working well on gas?

PS Had a fantastic trip! The Escape 21 is awesome, lots of folks wanted info on it. Saw 3 21's (2 in Texas southbound and one in Oregon eastbound) a 5.0 TA (Bob's - we visited with them in Mesa Verde) and a 19 coming into the Great Smokies as we were leaving.
