Hey Danny,
Hmmmm - I
thought there was supposed to be a stamped number in the front end somewhere - besides the one on the foil stamp.
If not then you might look into registering it as a homemade unit. I know some states will require you have a receipt for the materials to make a trailer - might be worth looking into. I could only see it being an issue for a future sale.
Better yet, just tow the whole thing down to the DMV and let them figure it out.
