It was painted by an artist with air brush. It took him a month to do the job, full-time. He had to totally repaint the trailer black before starting. It has 8 coats of the best paint you can buy. I am into the paint job $13000. The inside is diamond plate part way up the sides with the rest painted black. the floor has non-skid black deck paint. There are coat hooks and baskets for gear as well. Interior remodel: $1000. I bought the trailer new and paid $6500. It has only made one trip. Took it to Sturgis couple years ago. It is still like new. The artist doesn't normally do this type of work. I talked him into it, so it is truly one of a kind. As you can see it turned out well.
