If your idea of camping is a tent and half a toothbrush, this is the exact polar opposite of that. Big is too small a word to describe the EarthRoamer XV-HD. Built on a Ford F-750 chassis, this 4 wheel drive, custom built, self-sufficient expedition vehicle has every bell and all the whistles on board. Outside you get 46 inch tires, a hydraulic leveling system and a huge 2100 watt solar array. Inside, the full walk in shower is tiled in marble to match the kitchen counters, where a 3-burner induction cooktop hangs out with a Bosch convection microwave. A king size bed sits above the cab with a rear seating area that converts into another king.
The idea was to build a camper that could go farther, longer, so the XV-HD comes with 115 gallon diesel tank and 250 gallons of freshwater capacities. That plus the solar and 4WD means you can go just about anywhere, for a good long while. – $1,500,000
