My experiance with bed covers, several types, is thay all suck. So I just went down and bought a new Yukon XL Denali with a sealing and locking 12' roof carrier that I used when I had to carry five or six folks on a trip, no leaks, no break ins. Easy, peasy, every body in the wagon, and away we go down the road, in style. Only thing with them, is when the electronics start to screw up, and they will, pull the eject handle.
