That is one of the guys from action motor sports. It is listed for $6300 on their website but a lot less on KSL. snap it up ... if I could talk my wife into letting me spend that money I would buy it.
Not sure about that probably not his personal sled, they sell tons of sleds there. Just remember talking to that guy last year about a sled and the number is for Action Sports.
It's probably one their rental sleds from their business in IP, High Mountain Adventures - I think is the name. If it is, that will explain the lower than normal price tag.
