Is your rv insurance going to pay for it? If so, they might have a company you will have to use? In 1 year, I had 4 windshields in my Monaco... #1, stress crack, replacement #2 was defective, #3 was broken by the glass company trying to get it out of the truck, #4 was fine. My insurance paid in full for #1, manufacturer of windshield paid #2, #3 was paid by glass company.
