Here's something to think about.......it could be used to your advantage up north in cooler climates......
On mine, I have the top white and the bottom black.
I wish I would have used ANYTHING but black or had a lot less black (thinner stripes and down lower).
When the sun is on the bus, you can lean against the white part.
Try that with the black part and you will burn your hand!
I can't really tell much inside as it is insulated pretty well, but I am sure it doesn't help the AC!!
Granted, this was this Saturday, it was about 90 degrees, we were parked in a parking lot at the amusement center where we took a heard of kids for my youngest sons birthday party...........the Pig is NOW officially broken in.
