I recently got the bolt together defender rack from pjmjr. It is a very sturdy rack, I can stand on it no problems, each cross bar alone that makes up the "floor" of the rack can support my weight (~150 lbs.) on their own. I have even created a setup so that I can hang my hammock off the rack, parallel with my XK, with no external mounts (trees, posts, etc.).

Ever since I got the rack I have caught the fabricating bug, I even made a little side ladder, which gets a lot of looks. I'm happy that I got the bolt together rack, as I'm hoping to eventually create more identical sections to be placed in between the current ones, so that the rack will extend completely to the windshield of the XK like a large "safari" type rack.
