Are There Any Folding Tonneau Covers for a GMC Sierra That Are Water Resistant?
GMC Sierra Owner: I have a folding tonneau cover now. Do you recommend any other covers? I mean, mine leaks. The water doesn't bother me so much, but I'm just curious if there are any other folding covers that might be better and also easy to install.
Sean: Well, I just want to pre-warn you that I was actually with Undercover for a decade and they bought BAKFlip and a lot of tonneau cover companies that are actually owned by the same company, which Truck Hero. It's the name they're owned under, and folding covers are as far as water goes, the Achilles heel of the industry. We've done everything from different rivets, screws, seals, gluing, processes, everything. Unfortunately, on a folding cover, you're not able to keep 100% of the water out. Now, there are things in place with the drain tubes and the rails are channeled like a gutter, it's supposed to push the water to the drain tube and out the head if the rain tubes are installed properly. Which is going to unfortunately, require either some cutting if you have those little black plastic caps in the front of your bed, or some drilling if you don't, in order for those drain tubes to get out of the bed, so that's going to be the toughest part of the installation right there. The rest of it you're going to get two rails and eight clamps, you're going to have four clamps on the other side. Then the cover actually comes with elevator bolts and star knobs so essentially you sit the cover down on your bed, you go to the very front close to the window, put the elevator bolts through, and then from the underside you screw the star knobs on and your cover's installed, so that's as easy as it is. Well, I'm not very mechanically inclined and I've done about 50 of them, so.
