LAFAYETTE, Colorado — It may be the only camping caravan that has ever conquered the famous Rubicon Trail: the EarthRoamer XV-JP. This two-seater camper is loaded with goodies like a queen-size bed and a hot-water shower. The electric 'Loftop' roof rises to create some 9 feet of headroom. There are also 25 gallons of available fresh water, a refrigerator and a 6,100-BTU forced-air furnace inside the vehicle.For off-roading purposes, the vehicle is equipped with locking front and rear differentials, an electric sway-bar disconnect, a Warn 9,000 heavy-duty winch and twin Dana 44 differentials. The batteries are charged by an 80-watt rooftop solar panel, or a 160-amp engine alternator can do the job when you are busy exploring the trail.Priced at $110,000, the EarthRoamer XV-JP is built on the Jeep Wrangler Rubicon 4WD Unlimited platform.What this means to you: Although it comes with quite a hefty price tag, the EarthRoamer XV-JP is the ultimate off-roading RV. — Mike Lysaght, Correspondent
