If you like getting outdoors and off the grid but prefer to lay your head on a soft mattress and a shower over a bath in a creek, then you might want to check out Earth Roamer, maker of luxury expedition vehicles.
This is the XV-LTS, which can carry 90 gallons of water, 90 gallons of diesel, has a 900-mile range, generates 1200 watts of solar power and has a 12000 watt hour battery bank.
Oh ya, and pricing for this beast starts at $438,800. Better start saving!
