I have had a 14' alum, boat and trailer, this week I bought a 15' Lund tri-hull boat, with out a trailer. I managed to use a friends trailer to get it home ( we had to adjust the 2 bunks greatly and the keel rollers), but wanted to know from the experts what I should do for a trailer. Can I modify my alum v-hull trailer to accept the tri-hull? Should I just get a trailer for the new boat? I have tried looking at internet pictures of tri hull trailers and can't get a good grasp of what the bunks are suppose to look like, long, short, roller, 4 bunks 2 bunks. Really confusing, it is a fiberglass boat and very heavy. If anyone can shed some light on this fo me it would be appreciated
