I have...
...a shorelander. It's a powerboat trailer that was used, and the previous owner had the dealer modify it with some roller bunks to what was needed for the boat. It's rated a dual axle, rated at 5000 lbs. with surge brakes, good tires, etc. Previous owner said the trailer was $400, and the needed modifications were another $300 w/ the brakes and one tire being replaced as well. Not bad for what he got.Look around, check eBay if you don't mind traveling to pick it up, you'll find the right trailer for the right price.JoshPS Check this link, it's a pontoon trailer, but would easily convert. Only problem you might run into is it's overbuilt for a 22' sailboat...http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem
