Temps inside fridge were consistently 50 F +/-. I spoke with Reace several times and really didn't resolve the issue. If outside temps were 70-80 and inside of trailer was cool, temp inside fridge was 39-41. My impression is the unit is not capable of maintaining a temp differential of more than 30-40 F. If it's 100 outside, inside the trailer has to be as hot or hotter. I wondered about the amount of door insulation and think I will try hanging a sheet of bubble wrap from the freezer door extending to the bottom of the door. Will also try removing the freezer unit. We just went with an extra ice chest in the back of our TV and a 6 lb sack of ice every other day. We used propane when traveling and camped at Walmart with 110 V power every 3rd day or so. Also discovered AC works well but is unbearably noisy at night. Any tricks to keep trailer cooler inside when towing? We wondered about leaving Maxfan on low and having a window opened slightly to move some air through the trailer.
I spent quite a bit of time with the Delorme installation & venting guide
cleaning up the back side of my 5 cu ft refrigerator. I also added an interior fan that mounts on the cooling fins, added a layer of Reflex bubble wrap
to the inside of the freezer door, a fan blowing out the top outside grill that I use when the temperatures are over 90°, and a layer of furnace filter to the lower outside access door which helped keep the flame from blowing out while driving. All in all, the improvements helped a great deal. I'm still not happy with temperatures over 100° while driving, but there are limits.
By the way, be sure you have enough air intake open if you are going to run the fan while traveling. I tried it & it quickly raised
the refrigerator temperature - I suspect it pulled air out around the door seal. Shutting off the fan almost immediately lowered the temperature.
