Finished up my trailer this weekend.
Started with a HF frame
3/4" plywood deck
Lockable tool chest
Assembled and used galvanized pipe to build the poles for holding the tires. Put a screw on T-joint at the top that I run a bike lock through to discourage people from running off with the tires easily.
I had a friend weld up a custom hitch, bolts into the tow hook receivers.
Loaded up and ready to go
