The trailer body is framed out!
I still have to build out the bottom frame work fer the trailer belly pan. I did drop the back end of the belly pan about 1.5" so the angle wouldn't be as fast as it was before.
I've figured that the diameter of the swivel is about 36". Still working on how to support the frame work fer that part. Definitely thinking of using foam so it won't add a lot of mass to the swivel. I just hope it will survive the vibrations.
I have a layer of Tyvek to add to the sides before I slap the Coroplast back on. I should be able to reuse the old Coroplast sides without too many issues.
I built a new rear bulkhead and will try flush mounting the rear tail lights.
