Registering a home made trailer in This Old Boat Posted November 15, 2017 I am working on a trailer to haul my kayak around. I need to ask a few questions of anyone who has experience with registering a homemade trailer in NYS. Specifically regarding documentation. Like most homemade trailers, there is alot of scrap and scavenged parts involved. I know the DMV requires me to provide receipts for materials that were purchased. Before I get too far down a hole, I''d like to get some feedback from folks that have done this. What am I going to need for receipts, and what happens if I don't have what they want to see because it was scavenged and spare materials? PM is fine for the conversation as well.
