Well, the P-E is in and I'm a happy camper. I still need to adjust the latching receivers in the rails, but that's not a big deal. To summarize the installation:
1. The quality of the product is quite good

although I'm not in any position to give you a comparison. At $735 delivered for a SCrew, I thought the price was good too.
2. The quality of the instructions was mediocre at best

I guess I was expecting something more of a "Rolltop Installation for Dummies". The pictures were too small and one was not even referenced in the text. In all fairness to P-E, you can go to P-E's website and download instructions from there, as well as take a closer look at the images.
I've tried to provide some additional info in
my gallery. Perhaps some of this info, when combined with the instructions, will be of some help.
