Rear barn door window protection for GU Patrol

[TimE]

If you're packed to the hilt and cant see out the back anyway, I cant see any problem using core flute.

I'll get a price from my laser cutter as $190 plus sound very $$$ to me, leave it with me
Does the rear wiper just sit on perspex?

TD, not too worried about their price, seems reasonable given R&D etc,. Obies wanted $295 for their similar solution a couple of years ago.

I'm never packed to high when towing the camper, I like to see out the back window to get an idea of what the camper is doing. I assume the wiper sits on the outside of the perspex, just don't use it unless you want scratches.

Edit: This pic from their site shows wiper on outside of perspex
