Dale Earnhardt Jr may have been half-joking when he told GM designers he wanted a train horn on his new truck -- like the one he has at home that was bought on eBay -- but that's exactly what Earnhardt got on "Big Red," his custom built 2007 Chevy Silverado crew cab.

The truck is designed after a truck Dale Jr actually owns. He has an older Silverado that sits in his driveway in North Carolina. He's customized it himself, with a little help from his buddies -- and it really does have a locomotive horn.

This is definitely the only truck of it's kind, but based on public demand GM may build a production version of it for you. Get a price for a truck like this or any Chevy truck at Automotive.com

Junior gave GM designers his opinions on the truck's design, from the custom upholstery to the light bar -- and , yes, the train horn.

The truck is jacked up with an off road suspension, and sits on custom 1 of a kind 20" alloy wheels.

The roll bar with integrated lights is in a "flying bridge" style -- and looks like it belongs on a mega-yacht instead of a truck.

The truck's interior is done in a rich black leather with Dale Jr signature embossed in the seats. Te carpet, trim and headliner are also done in all black.

There is even a 6000 lb. Warn winch bolted to the front end.

Custom Spectra Flair paint highlights an understated Dale Jr signature on the side of the truck.

In true off-road style the truck doesn't have a tailgate. Instead, a spare tire is mounted in the bed for a quick change.

A custom roll pan with 6" exhaust pipes sets off the truck's rear.

Custom No. 8 graphics and emblems give the truck an unmistakable finishing touch.
