I've been spending time looking at tonneau covers and think I have possibly narrowed it down to one called Undercover. Its a space age, over the rail, plastic material, strong and maybe the most weather tite cover out there. Does anyone have any experience with this product? Matching the cap with a new liner material from bed rug would make a nice user friendly protected cargo box. Money spent would equal just a Lund or ARE glass cap. Seems like soft tonneau covers are highly prone to leaks so they are out of my looking. I'd like to hear your thoughts!
