Some folks say the highest compliment you can pay a modified vehicle is that it looks like a SEMA show build. SEMA, the contraction for the Specialty Equipment Manufacturers Association, is a manufacturers' and builders' playground held every early November in Las Vegas, Nevada. (We're sure Las Vegas, New Mexico, has some mighty fine car shows, too, but that's another story!)

So when we saw this 2012 GMC Sierra 2500 HD Denali on RYNO, we were intrigued and rightfully so. According to RYNO seller Mario Mazzarella, this 4x4 Sierra features a 6.6 liter Duramax V-8 turbo diesel, an Allison automatic, a 5-inch turbo back exhaust, an 8-inch exhaust stack in the bed and a list of show mods that keep an audience's attention from one side of the Las Vegas Strip to the other.

There's even a celebrity backstory with this ginormous GMC. Its previous owner was Lydon Murtha, the offensive tackle for the Miami Dolphins.

So, if driving a retired SEMA show truck is your idea of tailgating in style, this could be the "Dolphin"-itive Denali for you. Remember, you saw it first on RYNO. This GMC Sierra 2500 HD Denali is RYNO Classifieds' Truck of the Week.
