Yeah. I built a shield also out of roof flashing. I think the best thing would be a powered roof fan in place of the top vent.

Yeah the tan paint doesn't help. I know I can sure feel the sun in the morning if the nose is facing east. When I check the fridge it wa sitting at 37 so feel okay about things.

Shield? Do you have pics?
My temp varies from 33 to 38 on cooler days and mid 40's on hot days. Whats the purpose of the shield?

I hear it directs the heat to the upper vent instead of letting it hang around the big cavity above the frig. I haven't noticed a difference.

Some folks have formed flashing into a gentle 90° curved sheet to smooth out the corner. Is that what you did dcheatwood?

That's the way Palomino installed it in my trailer but it is also supposed to stop the hot air from building up in the gap from the top of the fridge to the roof.

Pics of two vents in slide. Three fans inside upper vent. And metal flashing above fins inside upper vent. Sorry so bad. Shooting up into sun.

So you went from behind the fins of the fridge with a bend / radius to the top of the vent sort of? This stops the hot air building up in the cavity above the fridge. Im gonna look at mine and see what I can rig up.

Yes. I sort of cut some slots in it on each side so i'd have something to attach to the wood and the sides of the frig with staples, and the main deflector lies across the top of frig and curves up to the top of the vent where I stapled it to the wooden frame there. I'm not convinced it helps but definately couldn'd hurt. I feel like some of the heat was escaping into the living area from around and above the frig.
What I'm planning now is to get my hands on a white vent and try to mount a larger fan to the inside of it to act like an attic or exhaust fan that pulls from the bottom up and straight out the vent. I plan to cut out all the vent where the fan is and put a shallow roof vent over it to stop rain. Since I seldom dry camp, and when I do it's winter, I'll do it with a 110V fan if I have to.

Really admire your persistence in dealing with this problem!

I think I'll try to fashion a similar deflector on top of the fins, as I can see where heat would get trapped in the space above.

Also, with mine, at the top of the wooden baffle (piece of panelling) there's a space of about an inch and a half (horizontally) between the baffle and the fins. I'm wondering if much of the airflow is taking the path of least resistance and just exiting the outer vent without even entering the cooling fins.
I may take a piece of aluminum and extend the baffle up a bit further and bend it inward toward the cooling fins.

I was concerned about airflow too. I can only assume that's why the paneling was in place, to force air over the fins before exiting. However my freezer is cold so I guess the upper fins are OK.
