How can these guys charge over $85 for a part that you have to drill yourself to mount the bracket? If I hadn't gone on a trip this weekend I would have returned everything. The insanely overpriced price for what you get and having to do everything by hand to make everything work is annoying. Oh, and as others have said, there is no documentation. It took an hour, a center punch, a few good cobalt drills. and put a lot of thought into making this "technical solution" work. It's still too far from the hoop and any idiot can pull out the pin and pick the expensive lock I bought from them. Save your money and get a basic Rotopax mount. If you plan to use a spare tire mount, use a different method to lock it in place. I now have a replacement fuel tank mounted on the back of my '98 Wrangler, but I spent too much money upfront and too much post-purchase effort to call it a good decision. It really works when you're comfortable.
