I read all the reviews and thought this would be perfect. But first off the thing leaks like crazy, leaks on all four corners and in the middle seams.Then because I live on a dirt road I thought it would keep the dust off things, no such luck. This is like a dust vacuum...it actually sucks the dust into the bed from the outside. If you have the plastic bed rail covers it is even worse. The dust comes in under the bed caps. So I have to silicone under there too. I have plugged every hole I can find and still no luck...tons of dust.I really like the fold up portion but I am really disappointed that this thing leaks and sucks in the dust.So considering that the only thing it works well doing is to keep people from stealing things...but awfully expensive just to do that.Good luck...
