The tailgate will only support the weight for a few tough trails before it tears the sheet metal and drops your tire in the trail. I have used swing away and swing up tire carriers on my zook and there is one thing I have learned that covers them both. If you do any difficult trails, you need to make sure any carrier that you use attaches to the cage as well as the bumper. If it only connects to to the bumper it will shake using the bumper as a pivot. I put in an additional cross bar that connects from left to right between the rear uprights (Full Cage). It sits right at the same height as the top of the tailgate. I then have a bracket that come of of the tire carrier to connect to the cross bar. It works well and keeps the tire (33/12.50) from doing the hippy-hippy-shake. <img src="/forums/images/graemlins/kewl.gif" alt="" />
