Here are some pics. I used a 4x6 board I think and beveled the edges and mounted a simple light bar to it. It has been on for around 2 years and hasnt tried to break or fall apart.
I would paint the rack black and use as light of materials as I could. I am trying to figure out a clamp that would work to secure it to the rails or rain gutter.
This may be too much trouble than it is worth. I just wanted your opinions on the matter. I love working with wood and my step dad is a carpenter so we could make something pretty cool(he didn't help me with the bumper)
Let me know what you think.
Here is a wood floor we put in after patching all the rust in the back:
The floor is pretty scratched up now but it works great.
