My insurance company has a national RV glass agent they pass a replacement clam to manage the process. In my case State Farm used a company out of Oregon to locate the glass, seals, and an installer. I am presently in Arizona and am in the mist of the process again, (darn trucks slinging rocks). One of the things I confirmed was that State Farm holds the agency responsible to get the repairs done correctly and do any follow up if things go wrong.
If the RV drives well and the tires do not show uneven wear I would have an RV glass installer look at he windshield and the area around the windshield. My 1999 Allegro bus is a fiberglass end cap. I noticed on the last install once both glass pieces were removed there appeared to be a bit of flex in the fiberglass.
I carry full coverage plus glass breakage on my rig and just call my agent if I have glass problems and will be in one location to get the repairs complete.
