I was kidding. When I bought a trailer, indeed the bigger cost was the vehicle. Fortunately, timing was right, it was time to replace a car so the cost of a tow vehicle was incremental to replacing needed transportation (business car allowance helped). I have a Nissan Armada that though it might seem surprising, pulls the boat just fine up and over the mountains
Thinking out loud as to ways to increase one design event participation - Some time ago, Bill Kneller talked about buying a J/30 fixer upper so the class would have a loaner boat. Seems a trailer would have shared benifits if owned by the class
