I'm telling you... . Checkout the Truxedo low profile, I think you will find it a better unit than the Agri cover.
FYI - Have also owned the Pace Edwards roll-top, seems as though their quality has gone downhill the last few years and the price has gone up. Nice unit when they work, but give it a few years and you start having problems with the roll-up. Not only has this happened to me, but a buddy who has one as well as my brother, thats why I did not even consider a 3rd Pace Edwards for this truck.
