Steve,
I just had my windshield replaced Wednesday in Santa Rosa, CA. I called RV Glass Solutions. They shipped the glass to a local installer they use. Excellent job and RV Glass Solutions handled the insurance claim. I thought about driving to Coburg, OR to have them do the job, but they said no need, they have authorized installers nationwide.
I would not hesitate to call them. Depending on who they use locally, they may or may not be mobile installers.
