Not waterproof at all
I read reviews it's my own fault. Pretty disapointed with the cover. I think they need to make some modifications on the rail system. Drain tube at front and back would be a great improvent. If you live anywhere that it rains much like me in oregon your stuff is gonna get wet under this cover. I do like the way it looks though. If you live in a dry area it's probably good
Real nice cover.
I had already seen this cover on a friends truck so the decision was pretty easy. But if you're considering the TruXedo which is similar design to this one with cross members consider two things. 1) The rail clamps on the TruXedo are external so count on lots of leg scraps. 2) The locking hardware is mostly plastic on the TruXedo where on this one it's all metal. When you lock down the back it takes a bit of force and you get a nice solid snap when it's locked. Dry as a bone also!
