They indeed a very expensive
as far as I know airstream supply is the only place to get them and the seals for them
both of my 345 airstream windshields have large cracks in them
I never have $2000 laying around to fix them.
money is always gone to the smaller projects (heater 1, heater2, at least 6 other window issues, steering, suspension, tag axle issues, fuel starvation, almost everything electrical, etc.)
luckily for me they have not completely shattered and I have not received any tickets for them... yet
I have done some research on this form another post any say use a RV shop. some say a truck repair shop should be able to do a good job. I will be watching this post with great interest as I am also in desperate need of “economical” windshield replacement
I even once went looked at a very run down 310 motorhome it was selling for $3000 and I figured it had at least $8000 in parts but one of the windshield had a crack in it, the entry door did not work the engine cover was cracked and it was missing one of the two bumpers I needed
Again if I had $3000 laying around I probably would’ve bought it for the parts but if I don’t have $2000 to spend $3000 is just a dream. Again I hope someone with more knowledge and a better idea adds to this post.
On another note I am a big fan of the cable TV show wheeler dealers they recently did a car that needed a windshield. They went to a place (I think in California) where they can take a windshield from another car and cut it to make the windshield you need... HOWEVER the donor windshield needed to have the same radius bend on it, and I doubt anything has the Bends in it that we would need.
Also on this forum some people mention I think it was the GM motorhome had a windshield very similar but as I remember nobody was quite sure if it would work, it’s price, or if it Even still exists.
I wish I was of more help to you
