Finally got around to building some. Very simple but effective. Worked the original bumper plate into the design so the tube doors will help support and maintain the correct door opening like the factory doors do. Used factory hinge plates and a factory door latch, works sweet. Closes/opens just like the full doors. Thought about another tube running parallel with the top of the bed side but once I mocked it up and sat in the seat, I decided it would get in the way. It was high enough so that it took away from the reason for having tube doors in the first place IMO, to be able to lean out and see that front tire. These doors tie into one of my most recent mods...quick release hinges. I can swap out doors in under 3 minutes now.
