Anything under 10,000 pounds they just register it as home made.
Last time I took a title in for a trailer under 10,000 pounds the gal convinced me to register it as home made because it was cheaper and she didn't have to twist my arm, but I got to thinking...
What if, on the off chance I got stopped and got Mr. Nosey

What could he do to me for having a homemade trailer with a VIN and a registration with NONE?
Could he get me for a false registration, even though my DMV supports doing this?
Granted, the tongue on the trailer in question had been modified and there is no actual VIN showing anymore, (I checked EVERYWHERE), so it skates by as home made, but I see numerous factory built (Ergo "VIN-ed") trailers every day that have been licensed this way and I gotta' wonder what happens in a state where it matters to them?
Mark.
