I'd like a trailer for my Model IV. I've been looking for a deal on a used boat trailer to convert but having failed to find anything that I like, I'm now considering building one. I have all the tools necessary but am unsure about the design. I'm including a couple of drawings of what I have in mind. It's based on a number of trailers that I found via Google but those pictures lacked detail so I had to fill in the blanks. Any advise would be appreciated.
