While on Lake Havasu last year, my boat was hit by a houseboat and totaled - leaving me with a 2 year old trailer (used for 1 season) that I now have no use for.
It has 4+ spare, everything is in great condition. Tows straight and true, 7 pin hookup with surge brakes and disconnect, and everything on it is adjustable - the axles, the bunks, the wench. This trailer can handle a big assortment of boats as is, and there is extra length on the tounge that may allow even longer boats to fit. It was set up for a 21 foot Jetboat (Cheyenne day cruiser, looks like a southwind) but because I spent extra for it to be fully adjustable, it can fit many boats.
