I have a new one that will be put to use this season..I talked with several current racers using them before buying one and mostly all positive feedback..mine is going behind a 3500 Cummins w/12ft overhead camper.

The only thing that I could come up with negative was having to get out and manually locking the units steering for backing up..but really not to big of a deal.

I think getting the latest model with 15" wheels and tires would be a huge plus to consider.
