It’s a Ram 4500, and its 16-foot-long bed has to be one of the longest beds in the world. The pickup has been stretched out to a 205-inch wheelbase to accommodate the gargantuan bed.

And you thought your pickup could haul. An off-road truck super fan has built a Ram 4500 with a 16-foot-long bed, twice the maximum length that the factory offers.

When the 4x4 Crew Cab is built, it doesn’t have a flatbed—or any bed at all. It’s up to the buyer to install whatever they want, be it a utility box, a dump bed, or whatever.

You can bet Ford intends on regaining its crown with the next F-450. That would set the stage for a Ram 4500 or 5500 pickup, giving truck customers two 10-lug options for their tow machines.
