I bought and installed the UNDERCOVER myself , cost under $600. I love it, it is very light , easy to use, and it comes with hooks to mount in the garage to hang/store it on when you take it off the truck. I installed it in less than an hour myself. The only part I needed to by separate is a new flush style tailgate cap because the one that came on my Chevy had a flare at the top edge that would not let the top close properly.

Thanks all, but I need a roll up one, way to often I am some place far from home and buy something that I didn't plan on and need an open bed. I have it down to the Peragon or the Jack rabbit.
I have seen the J.R. in person and it's nice but when you read about the Peragon and see pictures of it I think it's better. I just wish somebody had one for a while for some feed back.

I have not put my hands on the Peragon yet. But I have sold and installed several of the Pace Edwards Jack Rabbit. These units are no longer sold in my store due to quality issues. We have to work on 90% of them after the sale. Not worth it IMO.

Out of curiosity I thought I'd check out the Peragon. (wanted to see if there was a better mouse trap)

Paragon install

I Also checked out a bunch of threads on "the Diesel stop" it seems the Roll-n-lock is the only one that is dry and has a seamless top.

This One and the Retrax also look good in the reviews.

O.K. now I'm done
