Currently have a Extang Solid Fold 2.0 that has developed a leak. Not a "leaks a bit at the corners as most foldind/rolling covers tend to do" kind of leak, but a leak at the hinge going across the bed. Extang CS was great, and shipped a complete replacement to my Truck Accy dealer.
But, tbh I've never been completely thrilled with the Solid Fold. It tends to slide a round a bit on the rails as the springs are (imo) relatively light. The having to go on both sides of the truck to unhook it was a bit of a pain. And, the rubber side sections would fall off easily when folded up. Also, the "2nd" fold action was pretty heavy, lifting two sections of panel above your head with one hand.
Anyway, my shop agreed to let me "upgrade" the replacement to a different cover. I basically looked at the same options I originally considered - the Roll N Lock, the Undercover Flex folder, Undercover hard top, and a few shell options. One of my original issues is that I really didn't want a rail system in the bed, which is the main reason I chose the Solid Fold in the first place. But I've gotten over that, as it does severely limit you choices in tops. I also really preferred to not have to open the top to open the tailgate. It might seem silly, but I open the tailgate 100-1 easy over having the open the top, so having to lift a hard top or open a slider (in the case of the old style Roll N Lock) every time wasn't something I wanted. So that pretty much eliminated the hard top. Cost eliminated the shell, so I decided to go with/ended up with the Roll N Lock.
I actually wanted the Roll N Lock when I purchased the Solid Fold earlier - but due to the rails, and by buddy talking me out of one b/c he hated his (due to canister in bed), I didn't get it. But this time I decided to get the one I really wanted. Latest version doesn't require the connection to tailgate so it doesn't have to be opened to lower tailgate. Canister is small enough that I don't think it will be an issue for me. I never "fill" my bed, mainly just load it with fishing or shooting or hunting gear. I went with the Aluminum version vs the vinyl topped version. Should arrive in a few days, so hopefully will have it installed next week.
