This truck spent 2 years as a work vehicle in France, then the couple who own it now purchased it and converted it into an RV. It has two diesel fuel tanks on it, the silver square tank in front of the rear wheels is one of them, the other is on the opposite side. Each tank holds 100 gallons of fuel and at 10 miles per gallon, this thing has a 2,000 mile range between refills.
The rooftop is covered with solar panels, enough to generate 800 watts of power in full sunlight. That power is stored in a bank of 4 large batteries for use at night. There are also two alternators on board, one to charge the two batteries that start and run the engine, the other to charge the four batteries that run the coach, in case there isn't sunlight for several days.
Beind the rear wheel is a box with a generator inside. The generator is used when they need to run the washer/dryer inside the coach.
While they are parked in a campground for the evening, this vehicle is designed for boondocking! That's extreme offroad use. They were not plugged into the power outlet at the campsite and have no need for the electrical grid.
Inside the coach is a bathroom, kitchen, and a sofa the converts to a bed. There are storage cabinets and little else. It is a spartan existence, but one that will enable them to take their desired trip. The started in Halifax Nova Scotia, driving through Chicago, Yellowstone National Park, and on up to Alaska. From Alaska, they will drive South until they reach Argentina in 6 months where it will be loaded onto a cargo ship and transported back to France.
Sadly, there is no embroidery machine inside this one!
