There are already threads here on ExPo about that truck and the owner's previous vehicle - a super-duper Mog with super-duper trailer.
With the Mog as I recall, he never actually used the thing - it ended up just sitting on display at some museum of art. Once, he took it out to the desert for a photo shoot, but he lunched the tranny because he'd pulled out the Mog engine and tranny and replace it with a small block Chevy and a IIRC, a Turbo 400.
Basically, this guy spends millions having people design and build these super-duper, super-useless land yachts - and then he pimps it all over, but he never actually uses the damned things. Self-aggrandizement on steroids. A.k.a., wanking.
