We ordered one from Nextrail. It's being custom made for this particular boat. The owner told me that he makes all the trailers for the Wellcraft company. It really worked out well because the trailer manufacturer is only about 15 miles north of where the boat is located, so we can pick it up on the way.
We really weren't looking forward to dragging an empty trailer almost 1000 miles so this way it worked out great. We are probably going to hit Tampa on the way back from Naples to see a friend and do some running.
Any suggestions in the Tampa area?
