attaching a tray off the back

When I decided to hang bikes off the back from the hitch, I left the small square cross bar the hitch is mounted to and finished up welding all points the hitch and cross bar are welded to each other and the frame. They are only welded from the top side from the factory. I still don't think I would hang more than a couple of bikes though not the strongest set up with the small cross bar. The stock tire and carrier weigh in at 77 lbs, but I have seen a few pictures of  pods with way more weight back there, makes me nervous though because of this video. I did add a rear bumper/sewer line holder + bikes is 117 lbs total out back but the bumper is not attached to the hitch.

 I like your round window in the door and the submarine decal.  I've added a boat port hole in my door (it opens) and have been toying with the idea of adding fish scales and fins, but at this point it's just a malbec induced dream.
