86Scotty and Glider:
I have the Danhard A/C. I tried it out yesterday while parked in the sun, and it seemed to work good, but it was only about 80 degrees outside. I did not block out the sun with a curtain, but I did have the shades pulled down on the other four windows... we do not have any side windows, but SMB insulation is a big plus.
While we were parked, the wife and I discussed things we can do to help cool the van down in general in preparation for more extreme heat...say, 95 to 100 degrees. I still intend to get the latest type of window tint that will help to this end, but would like to hear about what you guys or other folks have done to help stay cool when parked.
Thanks very much for the comments, and if you can add anything else, please do!
