reset a Class A windshield in the Pittsburgh area

We have a 2004 Class A National Sea Breeze with a split windshield. On the driver's side, it has shifted and needs to be reset. We had the same problem with the passenger's side when we were in Florida two years ago. Found a company that came out and reset it in about an hour, and have had no issues with it since.

Now we are in Pittsburgh with the same problem on the other side, but are not able to find anyone that can do this. Does anyone know of a good glass repair company in the Pittsburgh area that can work on RV windshields?
