Also check the old Star Auto Glass now known as Reliable. They do have a Tucson location but have a network of shops around the Phoenix area. The Tucson location generally has a good reputation but I don't know how their RV techs rate but if anything like their other locations, they do good work both on windshields and repairing the foggy glass issue for reasonable prices.
