In all reality, the thing probably does pretty good. The gearing in that rear is most likely low enough to where that sucker could pull close to anything with that engine . He probably used that bed to be able to match up to the cab and tire position, a proper bed probably wouldn't fit. The mudflaps, well, DOT out west has zero sense of humor about raised vehicles and exposed tires. At least this guy has one of the rare few legal rigs out there. Paint job looks like a company logo.
Kind of liiks like someone had the thing built for a company and is trying to recoup their costs of the build, but the guy is wet dreaming if he thinks he's getting that much for it, unless some other clown with deep pockets just happens across the thing and has to have it.
