This mega beast made its debut last week at the 2017 SEMA Show--and it isn't your grandparents' Winnebago. The new XV-HD is hand-built in Colorado and utilizes a 4WD Ford F-750 chassis with a 6.7-liter Power Stroke V-8 diesel engine.

"The HD is our most innovative product yet," said Tyler Tatro, EarthRoamer's head honcho, in a statement. "It utilizes state-of-the-art construction and systems to bring comfort and functionality to the next level."

Designed to accommodate up to six people, the latest super-sized EarthRoamer rolls on massive 46-inch Michelin XVLs. It has a rear air suspension with Fox shocks, hydraulic leveling, hydraulic front 30,000-pound winch, and Baja Designs LED lights.

The EarthRoamer also has 2,100 watts of solar capability with panels on its roof, a 20,000-watt lithium-ion battery bank, a PTO-driven hydraulic generator, 250-gallon fresh water capacity, and 115-gallon diesel fuel capacity.

Inside, it features a full bathroom with a separate shower, washer/dryer, full kitchen, in-floor heating, a booming Bose Surround Sound entertainment system, and top of the line King Ranch trim in the cab.
