Year and a month on my Bak X4s and still zero issues. First delivery i did have a broken weld on the cover so i had a small bulge. Bak asked for some pics and then sent me a new one. No issues other then that. Not 100% waterproof but only by the tailgate. I know people mention the rubber seal on both sides doesn’t sit flush when they first installed it. Mine was the same but having the previous version of this cover on my Rebel i knew a few days of sun will make it mold properly and seal correctly.
@Johnny@JustBoltOns if it wasn’t said above stopped carrying their products as they did have a lot of issues with them. I still love the cover. Those plastic end caps i was also concerned with but mine are still there. This cover is also good for using it with the rambar and or the Go rhino sport bar 2.0.
