Mike, consider an alternative
When I bought my 272 in 1994, it was stored on a cradle resting on a trailer belonging to the previous owner. He asked me if I wanted the trailer, and I said no because I had no vehicle which would tow the boat and cradle. If your boat comes with a cradle, it can be easily set onto a trailer and towed that way. That's exactly what the previous owner of my boat did to save on winter storage fees. (He also had a place to park boat and trailer at home.) The cradle for my 272 is light enough that two people can pick it up and move it. I took it home two years and rebuilt parts of it with native oak which is what all the support pieces are made of. The total cost for the lumber was about $35.So... rather than remodel a trailer, consider hauling it on the cradle.Tom
