So I towed the trailer down to a friends house last night to help me weld up the broken bumper. That is nice and silid now. While I was there, I noticed he still had the pieces he cut off another trailer ready to go to scrap... so I decided to weld those up too... so now I have skid guards to protect the bumper from steep driveways ripping it back off again.
Bumper is welded... Windows are coming out... no more pictures for a while until it's done! :)
