I have one, but have note added the hitches to the RV yet. A friend of mine is going to do it for me when he gets some time.
Didn't notice you location, but check craigslist before making a long trip to Texas. I considered buying new,'but shipping would hurt! I found mine in Craigslist while locating a golf cart for a friend of mine. Bought the tricked out cart and the swivel wheel as a package deal (good deal). The guy had removed the wooden floor of the swivel wheel installed diamond plate. He also added railing to three sides. Came with a spare wheel / tire, all the tie downs, and a custom adapter to tow it with a truck (single hitch setup). He said that he wouldn't haul the golf cart on the adapter setup, but he made it to move the trailer around and to get it home when he bought it. I hauled the golf cart home in the bed of the truck, but did drive it up on the swivel wheel to see how it fit when I got home.
