Here's mine: http://www.jeepforum.com/forum/f37/r...-take-1106444/
I left the ends open so I could haul lumber on it, and I'm really
happy I did.
If I built it again, I'd use all 1x1x16ga. steel. Mine has heavier gauge load bars, but once it's all welded together, 16ga. would be more than strong enough.
The JCR rain-gutter mounts are great. I think it's worth the extra money to get six instead of just four.
The spray-can bedliner is worthless. If I had to do it again, I'd just pay the price to have the whole thing sprayed with real bedliner, or powder coated.
