Don't get rid of the original vent cover because several reviews on that product indicate that it starts to disintegrate after a couple of years; broken solar cells (self destruct), cracked plastic housings (maybe very thin cross sections or poor quality, non-filled resin).

So, are you guys thinking that the roy vent is somehow causing the refer to blow out or it keeps the refer from properly exhausting the heat?

My thought was turbulence due to the non-tapered OEM shape while on the road could cause an issue with running the fridge on LP - just a theory.

Every piece of plastic on my roof gets covered with a few coats of Krylon Fusion paint because of the UV protectant. Has worked for me to protect plastic from embrittlement for a lotta years. Worst case is I just make a new one.

I've got the smaller 4.3cuft with the stock roof vent and refrigerator has always performed well on the road with the LP always on while traveling. I did however put a baffle in the back to eliminate all the dead space behind the refrigerator and a mesh filter on the inside of the lower vent cover to keep the flame from ever blowing out while underway.

AND the same in MILLION DOLLAR + mohos. Just check out RV.net and IRV2.com

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.

I travel with a cooler with ice. But, I also know how to pack the frig. Few folks do... pay attention when you buy your food. So much doesn't need to be refrigerated... just kept "cool." If it's NOT under refrigeration when you buy it... it doesn't need to be kept COLD... just "cool."

What's really helpful is I prefer my beer as in Europe - unchilled!

Any chance of some pictures of the baffle and mesh? I have the same frig and have similar experience to yours. Really worked better without the freezer.
Is your fan mod up and running? .
Thanks

Hi Dave! The baffle is really hard to photograph but there has been a lot of discussion on the topic on this forum and I think Dometic has a drawing of a suggested baffle form.. Others on this forum may want to chime in if they have a sketch of the baffle I'm speaking of. I got the idea for the mesh filter cover on my vent from "cpaharley" (Jim) and it works fine. I think there is also a picture of one here in the gallery somewhere. I'll look.

My fans are operational but I expect to receive the fan grills in the mail tomorrow and then I will finish everything up and take a few pics for the forum.

Steve

Took my trailer to a service center to have fridge checked out. LP pressure was at 9.5" WC, they changed it to 11" WC. Now getting temperatures under 40 degrees F in the fridge, on propane.
