What a drag!
I had to replace one of the fixed windows on the back side of our trailer due to a loose nut behind the steering wheel. Also had some body damage to take care of. My insurance, minus the deductible, paid for it & I had it repaired at a local RV shop that I both trust and is WAY closer than the selling dealer. They had to get the window from FR. I don't recall the cost, but could get it for you for perspective.
While that was all happening, I had TAP plastics cut me a piece of dark tinted acrylic, radius the corners and after we broke out all the remaining pieces of the old window, we glued the plastic in it's place and you could not tell the difference from 2 feet away! Kept it there for two campouts, about 4 or 5 weeks while FR shipped the window to California. If insurance had not been paying for the work, I might have kept the acrylic in place for longer it was so good. Even my wife, who is very, very picky about such things, thought it looked great, inside and out. Cost about $35 at TAP.
The acrylic option may be a way to go for you
