Now what do you need to do to get it legal? Does someone have to inspect it? What about a title?
I am planning on getting it Titled and Registered, I talked to Boyd at Pard's (they used to make alot of trailers) he said, that after the trailer is done you take it to the High Patrol and have them inspect it, the trailer must have the following:
proper rear and clearence lighting(I've got the reqired ones at each corner and am planning on adding more at the fenders),
safty chains, fenders, secured decking, break-a-way brakes (got the pull switch $9 and I have a battery), a coupler pin, and reflective tape along the sides (I have some leftover from overhaulin' another trailer)
I'd bet they won't like my rear set of tires (<2/32")
So once I've passed the safty inspection they give me a slip and I take that and the trailer to the DMV they inspect the trailer for a vin and require a "bill of materials" including all materials and there $cost$ (so they can come up with a base to charge you sales/property tax) some double sales tax paying here, but whatever (I don't have to include my labor and between us the whole trailed is made from "scrap")
After they have looked it over they issue a VIN plate, after affixing the plate the trailer can be Titled , and then registered normally.
I know many people don't register there trailers, I never registered Bubba, but they say it makes them easier to recover if stolen, Plus just for peace of mind I want to get it registered, I don't want some mean cop to impound it or give me a ticket or whatever.
