Hi all. Beating a dead horse, but it finally happened. Victim of the dreaded 100LL spill on the rear window. Immediately started to craze. RV -12 is 2011. Is there a new plexiglass window, or is Vans still using Lexan? For 9 years we?ve been so good and cautious, but the dreaded fast pump and then belch did me in. Thanks for any input.
