Have a dometic fridge located in the middle of the trailer. Underneath is a 4x10 intake vent with the exhaust coming out the roof. We are not of sane mind and go camping in temps that can reach 120F. The fridge really struggles. The AC runs constantly and i suppose the cabin gets down to 80s or 90s. I can access the refer intake duct by removing the electrical panel. There is also a 4" heating duct that i have abandoned. Thinking about using the 4' opening with a small computer fan to blow cool air into the fridge duct. With a baffle maybe to close it off. Or just a vent cover that can close. On the summer camping trips i would just tape off the the vent under the trailer, and turn the fan on. What do you think?

Just adding fans to the existing fridge vent should do the trick, without having to use your cool inside air.The hot outside air doesn't circulate through the coils as well as cold air does. Since the air is already hot going in, it doesn't get much lift being heated by the fridge coils, in order to vent out the roof.Adding some computer fans blowing out the roof vent should help that convection do its thing. Look for high static pressure fans, their blade design works better to move air through the roof vent.

might helpbut remember all the air being exhaustedwill be replaced by hot air from outside coming into the RVwhich will make the inside of the RV warmerhow much ? IDK, but its plain physics

Been watching videos. Especially from the Ford Rv AC people on youtube. He says the ambient air temp really effects the cooling ability of the fridge. For extreme cases like camping in 120F i think venting with the inside air should really help. Next trip isnt until July. Will post up the results.

Why not replace the fridge with a dc model that has a danfoss (secop) compressor, add another battery and some solar panels? It will hold the cool setting way better.

A/C is constantly onso you are on shore powerIMO the best option is replace the fridge with a residential120v compressor fridge will work better, and you can block off the both outside vents, intake and roof, and vent/circulate inside the RV
