If I had unlimited time/money, I would order a 2015 all wheel drive Sprinter next year (I'm guessing Mercedes takes orders in May for a September delivery like they did with the 2014s), have it upfitted by Sportsmobile as an all-diesel rig, where the stove, generator, water heater, furnace, and refrigerator would be all running from the diesel tank. It is expensive, but it would definitely be useful for boondocking, just due to only worrying about one fuel.
Very good point! Of course the Earthroamer is designed this way - an all diesel main energy source - supplemented with generous solar capacity.
However and FWIW, today many motorhomes can kindof operate this way if needed during short-term regular camping periods or during emergencies for awhile.
For example: Our small Class can operate off it's 4000 watt Onan generator for all of it's energy needs including electric cooling, heating, and cooking. For half-loads (running one 1500 watt electric heater or one electric hot plate for a few minutes with the heater turned off ... or even both for a few minutes), the Onan consumes about 0.4-0.5 gallons per hour on average. This means that off the main 55 gallon gasoline tank, we "could" get completely by with just the gasoline Onan generator running continuously from a nearly full main fuel tank for around 100 hours - 4 days.
