Im building a trailer because I feel I can build a better one than I can buy for less money. NO -- No boat yet just wishfull thinking. I can always sell this trailer. Im looking for someone who has built one to respond. There was a lot of talk but no response to my post. I want aluminum but cant figure out a few details: I-beam or tube? - weld or thru bolt? I would use steel though, just not as heavy as my old one was.
