Yeah, I've been pretty darn impressed with it. I've kept it clean enough for most of it's life, but the birds finally got it with some acid-rain(!) a couple of years ago and I have a little streak down the back window. It even stripped the black off the the still pristine Kayline label! Pisser!
Been waiting for the windows to yellow one of these days, as it lives outdoors and I just put a cover on it for the first time last week. The windows aren't looking brand new anymore, but they're still super clear for their age. Wanted to keep them that way, so bought the cover.
We'll see if I can get another 20 out of it. If I can get the green lichen and mildew out of the zippers and a few seams, I'll be happy.
