Hi Chris
two months now and about 10 days/nights in the camper in the Sierras with snow/rain.
The windows are doing good ( I actually changed the passenger bedroom one too).
The best advise is take your time to make the mod, I would say the most important is to make sure that your Dicor (I used 3/4 Dicor tape/roll) is uniform around so when you torque it is really sealing the window.
I would have liked an original window, but this is not an option anymore so I think this is the next best thing.
(shipping is not obvious, the second window came destroyed by UPS, I took pictures before opening and requested feedback from the seller before moving forward). The unit was not salvageable, the seller send me a new one that came with no damage)
best of luck.
Thomas
