Who doesn’t love some crazy custom project, right? The bigger and wilder, the better! Well, we’ve got something pretty damn big and and pretty damn wild for ‘ya right here. Say hello to Robert Nuccio’s custom GMC Motorhome 6×6, a heaping slab of off-road-ready, roll-over-anything, bespoke-everything-and-then-some goodness.
Based on the GMC Motorhome, the brand’s very own RV vehicle produced between 1972 and 1978, this 6×6 behemoth is anything but ordinary. Riding on six axles fitted with enormous knobby tires and custom airbag suspension, Nuccio’s Motorhome is over 10 feet tall! Gerald King from Finish Line Racing takes responsibility for piecing it all together, as well as documenting the build on his Instagram page.
Under the classic bodywork, we find a custom full-frame chassis. Making it move is a built 585-cubic-inch Chevrolet Big Block V8, which sends power to the ground through an upgraded 4L80 transmission. On a recent dyno run, the setup put down nearly 800 pound-feet of torque. It also sounds amazing through a pair of enormous side exhaust pipes.

This GMC Motorhome is 100 percent functional too. It’s got winches on deck from front to back, plus arc welders in the cabin in case anything needs a quick fixer-upper. Sitting in the hot seat, the driver has well over 100 gauges to look at, each of which is hooked up and working as intended, feeding back info on things like individual tire temperature and tire pressure, pyrometers, holding tank capacity, and more.
The cabin itself still needs some work, and currently remains stripped down and bare. But the fact this thing not only runs, but runs well, and looks this good at the same time – well, that’s nothing short of amazing.
The GMC Motorhome 6×6 build has taken a whopping 12 years to get to this point, and we’re sure unseemly amounts of money to boot, but we’re confident Nuccio won’t rest until his vision is finally complete.
