I found one of these on Craigslist for 100 bucks still new in the box. I already have the trifold bed cover and was wondering if this is an upgrade or not

 

It would come down to preference. I personally like the roll up ones as I need full access to the bed when hauling my KTM.

 

The cover you linked to is a Ford logo'd Truxedo Edge. I had one and sold it for the Bakflip F1. For a soft roller it was quite nice. Pretty water tight and kept great tension.

 

I pulled the trigger on it and picked it up yesterday morning. Installed it last night and you are correct, great tension and seems to be water tight as I took my truck to the car wash and the bed was bone dry afterwards.
