You oughtta move one state to the SW.  We Arizoniacs almost always have nice
warm cars to get into, like around 150 degrees F.

Thanks for the recommendation.  I'm in Colorado, but are typically
camping in the spring and fall when it is pretty cool.  A little solar
heating, through the darker roof is typically welcome.  It's nice to
come back to a warm Westfalia after a day of excursioning about!!
