New tonneau...
I took my truck back to the accessory dealer and they swapped out the leaky/ill fitting Flex/UnderCover and replaced it with their top of the line Retrax in aluminum. Wow! What a difference. Much nicer cover, works easier, can be set in any position, far more durable, the only downside is it cost over double what the Flex cover cost (to be fair, it's also heavier and it does eat up some box space where it rolls up at the front of the box) As far as the extra expense, I have a quality cover that actually works, so I guess it's worth it. In my old age I have gotten so I would rather have something of quality or nothing at all.
I will post some pics of the cover when I get back to my truck probably tomorrow. Also you can go to retrax.com Then I will try to find an appropriate thread/location and repost about the new cover there, so guys can find it if they are cover shopping. If an admin reads this feel free to make a suggestion for where to post it. Thanks fellas!
