Trailer advice

Hi Folks,

I’m looking to convert a used trailer for my FC but I’m a total novice. Any advice out there? I was hoping to use the shortest trailer possible to shave down on storage and shipping costs. I would remove the bowsprit while the boat is on the trailer. Also, would it be costly to upgrade axles so they can carry the FC? I see a few trailers for sale with 6000-7000 ratings. Should I worry about the frame itself?
