Got my Retrax bedcover installed and it looks great. I ordered from the factory an got it for $1070 shipped. They got it to me in 4 days, I highly reccomend these guys.
The install took about 20 minutes, but another hour for me to get it lined up. I am a little OCD so that didn't help, lol.
I will post pics soon, but I really like how this thing looks and functions. I'll update on durability and water tightness as needed. I also bought an electric tailgate 'lock' an am in the process of installing it. It is just an actuator that pins the tailgate lever but hooks to factory door locks.
I looked at every retractable bed cover made and am happy with the Retrax. It will lock in any position, doesn't need a pull strap and will open with the tailgate closed.
