I've got one on my Titan. I found a guy locally who bought the wrong one for his truck so I got a good deal on it. I've had it on for about a year and love it. It's almost water tight, but does get a little water around the sides of the bed when I take it through a car wash. The feature I like best is the ability to easily roll it up when you need to use the bed. Not like a hard cover that you have to fight with. When you lock your tailgate the tonneau cover is also locked, which keeps people from getting curious. This looks great and works very well. I'm very pleased with mine.
