That's what I'm suggesting, with no proof of any kind. I feel like we finally have the fridge working reasonably well when parked, and can't help but think that airflow around the vent(s), either top or bottom, is diminishing the natural convection (aided by whatever fans and such are running).

Exactly J Mac! For some reason, a lot of trailer trailer folks (all of a sudden) seem to think EVERYTHING needs to be in the refrigerator. Pay ATTENTION to the store where you buy... Even Unopened MAYO doesn't need to be refrigerated, nor tomatoes, or potatoes... etc., etc., etc. Dairy and fresh meats... YEP

I'm glad you found that and had it corrected. Fixing the gas pressure had the greatest positive impact on my refrigerator performance since I run 99% of the time on propane.

Does anyone have pictures of this "Texas Fan" option installed? I've scoured this forum and Google Images and just can not find one.

EVERYONE complains, it's not about the manufacturer of the trailer, truly. But, everyone expects perfection running on propane or solar. You don't like it? Stay home, purchase a "compressor" frig... like is in your home! And, y'all wonder why folks stay in "RV Resorts" where they're HOOKED UP to power.
In some cases, it is about the RV manufacturer, due to improper venting arrangements. In general, I agree that absorption refrigerator problems are due to the appliance, and the fundamental design is the same in all sizes and styles.

Not everyone expects perfection from an absorption unit, which is why many of those big RVs do come with home-style compressor-based refrigerators... right from the RV factory. And yes, that means being in a serviced site, or running a generator all the time, or having a big solar and/or battery installation... none of which would be acceptable to many Escape owners. A low-power compressor refrigerator made for mobile use, on the other hand, may be a valid option for Escape owners wanting to avoid absorption refrigerator issues.

Steve, thanks much. So it's 2 or3 12V fans with a thermostat and mounting bracket for $135. That's a bit steep. I think I'll work on a plenum surround for the fins with one fan on top - when I get my trailer!

Charlie, I have the 4.3 unit and it came with two fans installed by Escape that was standard equipment, not an option. It had a thermostat buried in the top condenser coils that turned on the fans. I bypassed the thermostat on mine and put it on a switch inside so I can turn them on anytime I want. Personally I've tested them during hot weather and never measured any functional benefit from them in my trailer. They are also a little noisy.

I also think the top exhaust vent is where to pull that air out. Make sure you get the vent setup Reace was referring to so that the air gets directed properly. Let us know what you eventually do and how it works out.

Charlie, I'm thinking that two or three of the fans like I put inside the refrigerator would be great installed up in the exhaust vent. Those fans are real quiet, pull a lot of air and two of them only pull .1 amps....hmmmm?!!
