The dually spacers are nice for changing brake pads up front without removing the tire - especially because your jack may not be tall enough to do it. Which is why getting the spare down may be a moot point. Can you even mount it by yourself? I don't know what a 46" Michelin weighs, but I've probably had that much weight on my hardtop before. I climb around on my roofrack while it's loaded with gear and never had a problem. My mounts are in strong points near the front and back, though, while that short rack would be weaker. Hard to believe he needs a swaybar with those springs, but it looks like a custom one? There's a lot of angle in that CV joint - wonder if there are seals on the ball. Unless he has super deep gears, it will never spin very fast, though. As usual, it's a monster 2WD.
