Bomb proof, enlist a friend
I have a 1998 Land ROver Discovery and fitting a roof rack to it was very difficult. The yakima towers were too short and rubbed the sides. So I bought the Thule Super High Foot towers. These towers are tall enough to clear the domed roof and the factory rails. They fit very securely to the gutter. I have complete faith in these towers holding up. Installation was difficult with one person so I would reccommed this be a 2 person job. The towers have to be pulled away from the vehicle while tightening the feet down. Again this is hard to do by yourself and if you're not careful the bars will bow upwards if things aren't aligned properly when being tightened. Once in place though the gutter feet really hold. I can shake the whole vehicle with the towers.
