Hey all,Does anyone have any ideas on how to set up my new trailer to accomodate my Venture 21?My original trailer is bent beyond usefulness and is slowly sagging. Currently I have about 3.5 inches between the starboard trailer tire and the hull (no fender - It won't fit anymore).I just bought another trailer of exactly the same length and I'm pretty confident that the V21 will fit nicely on it. Here comes the question:What's the best way to go about pre-configuring the new trailer to ensure that the boat will sit nicely on it? The cross members of the new trailer are located in slightly different locations that the original MacGregor trailer, the bunks will need to be slightly longer (10') to accomodate this. The keel receiver will also be in a different location (about 18 inches forward)And another:Has anyone tried using "Trex" the plastic decking material for trailer bunks - supposedly it can be cut/drilled/routed the same as wood, but it's actually plastic, thus won't rot - Is this a posibility?Any other general wisdom about switching trailers?Other caveats?ThanksGraham
