I bought a 5x9 utlity trailer from a surplus sale to haul ATVs and such. Need to get plates for it, but no serial number or rating plates on the trailer itself. Got a bill of sale in the transaction to prove I did not steal it, but have read conflicting things about gettin it registered. The axel appears to be rated for less than 4000# when compared to similar trailers, so has anyone done this that is willing to give me the rundown? Also, it is a single axel with no fenders, do I need to add fenders? Already have a light kit for it, so I have that covered.
