I have 3 roof vents and when I put the vent pillows in them all the temp inside got cooler right away. If you have white lids, replace them with black lids big diff also.

Good stuff, but I don't understand replacing white lids with black lids. It seems like it should be the other way around.
My fiver came with a black AC shroud and so I also got black vent covers to match. After some hot weather camping with one AC, I am thinking of replacing all black covers with white.

I would have thought the exact same thing. UNTIL....
I had a lid come off during a storm. Mobile RV came out and repaired and I forgot about it until a year later in Florida during summer.

I was walking thru the coach and all of a sudden I felt hot heat coming down on me. It was under the vent cover that had been replaced. I had not noticed he replaced it with a pure white cover lid!

And I guess I should edit. My original vent covers where a light gray color not solid black and he replaced it with a pure white one and the heat just blared right thru the white.

I was shocked of the difference it made. The pure white ones are actually hot to the touch with the sun on them! The smoke ones are not.

IMHO 80% of heat and ac go right out thru those not air tight roof vent openings. More vents you have the more loss. Pillow them all! :B

found at any camping store or online
IMHO the best ones have the silver on one side for more reflection/insulation.
