My solution for the MicroRV was to use a battery bank and 3+kW sine wave inverter. Recharge of the battery bank by engine running and solar. It would also be possible to run a big battery charger via a Honda inverter generator. When the big inverter isn't needed I was figuring on using a small one for greater efficiency.

For those who don't like to do the dishes:
EdgeStar Portable Countertop 6 Place Setting Dishwasher - DWP60ES 
Currently I'm wasteful and use paper plates, etc., but I still think it would be fun to bring out the fine china like my grandpa did.
Laundry day:
Summit Ariston 15 lb Combination Washer/Dryer - ARWDF129 ;p
For the ultimate in electrical stove top cooking effency, an induction cook top:
SINC1110 Summit Single Zone Built-In Induction Cooktop They use around half the energy of a coil style burner. You could also use portable ones too. That was my plan for the MicroRV.
Yeah, I did a bit of research on bringing all the comforts of home to the trail. Once you have a big battery bank for running the laptop for long periods, other stuff like microwaves, toaster/convection ovens, etc. looks allot more realistic. Stretch the battery bank a bit and cooking become possible. Stretch it allot, 400AH+ battery bank at 12VDC and even air conditioning is even possible, but only for 8ish hours on a charge

. Even the most efficient units are power hogs. If you put in a huge battery bank, install an alternator designed for long hot running. Balmar is quite reputable in that regards, but pricey. The other alternator I thought may be interesting is a GM CS144 in one of the moderate output levels like 140Amps.
Solar is viable for running laptops, and cooking, but not air conditioning. 8+ 200W solar panels would be needed for air conditioning and that just wouldn't fit on the roof. On the other hand an inverter generator run during the day could recharge the batteries for nighttime air conditioning. Many NPS campgrounds only allow daytime generator usage.
For the bears, there is:
Bear Shock Electric Fence for the Backcountry Note: All the bits are standard electric fence parts available at any good farm store. If I was putting one together, I think I'd use electric fence netting instead of wires. If you don't think this works, the forest service is using them to protect their remote camps in bear country.
