We have a vent right over our bed and hated that the sun would blast through in the morning. Since I was too cheap to buy a tinted cover I bought a vent cushion (Vent Cushion - Intersource D10-146 - Fan and Vent Accessories - Camping World). It still let too much light in so I took the cushion part out and wrapped it in a black garbage bag. Keeps the light out and the heat in!
Our vent cushion was a tad more money but has the silver thermal cover on one side. We get no light thru it and it is worth every penny for sleeping undisturbed by 4:30 am sunrises.
Do they make replacement vent covers that are insulated? That is, still lets in the sun in the winter, but you can still open them up if you get a warm day?

My solution was to build a light balsa wood frame, cover one side with black felt and place an inner liner of silver heat shield floor liner material left over from one of my classics. Attached on four sides with small squares of velcro stickers. Anxious to see if it all holds, will update when I've been out in the SP240. Oh, cost, about $3.
I have covers over my vents and use the pillows. Bathroom vent warped badly. I assume that heat trapped between the vent lid and foam pillow created too much heat and now leave the vent covers open in the summer.
I used this one for a while but in this Louisiana heat, the Velcro tabs dried up over the summer and it kept falling. So I ran two lengths of fishing line across the opening to hold it in place. Does work well if it stays up.
