Several years back, I bought a Canadian Army surplus M101 trailer from a military salvage yard not too far from home. Before purchase, I'd called DMV, asked about registration requirements and was told all I needed was a bill of sale and a photo of the build plate showing the serial number. When I went to the local license bureau (in NC, they're operated by concessionaires) with said documentation, the owner told me I couldn't register it without a title. I'd known this guy for years and our kids were in 4-H together but he wouldn't budge. Went to the office the next town over and got my tags with no problem, Some people are just pricks.
