Okay lessee here, got it from one of our racers who works at lbtrailers.com (Lance Pentecost, good kid) actually sold me the Showhauler when he worked at a different dealership.
It's an 07 on the Columbia chassis, 450 hp Mercedes, twin screw, 32'. This one is a little more pimped than the old one, corian countertops, superslide up front, rear slide with the closet in it in the bedroom, tracking sat dish, stainless luggage doors, powered awning, outside entertainment center and a really nice 12v cooler, all sorts of trick stuff.
Still haven't spent a night in it though, had a control valve of some sort go out on the way to the track last weekend, finally got it back from Freightliner in Birmingham Wednesday after they got the part in and put on. Not a huge deal but I hate service writers and managers that lie to me.
