I'm going to go buy the wood to finish the floor of a trailor I have been working on for a while. I started with a pop-up camper and stripped it down. Then I welded on side rails, wired it, put lights on it, and then I let it sit out in the weather and rust for 6 months. Now I'm ready to clean it up and floor it. What do I need to do with the DMV to get it on the road?
