Chris, I'm on the JK forum. Great stuff. The black trailer in the first piuc and the yellow in the last are fiberglass. The guy who built the yellow trailer is awesome He built that Jeep pickup from a wrangler. I have an XK (Commander) I want something to match the Commander. If I am going to spend $1K+ on a rust hulk of an M100 then restore it, why not have something done from scratch?
Here's another cool rig. This is the real deal M100/416
