I agree ; our first day of travel , as we retreat from AZ in the spring , west into the sun across the desert , is a killer .
Temps then are only mid 90's
We can't wait to make the turn north and get the sun off the windshield .
Then we park the coach in the yard till school is back in in the fall. No sense being on the road in the heat with bumper to bumper traffic to contend with .
