Re: 12V water heater?
It's actually jetfuel (isobutane... I think it's an alcohol/butane mix.Personal Cooking System (PCS) | Jetboil
The sytem is relatively small. If you were backpacking, i would recomend something else. But, it is small enough... and there is plenty of room for this in an FJ (even in the rear side jack compartment) and one of those small cylinders boils up to 100 liters of water. I dunno... it's good. IMHO, Nothing electric (12v or 120v) heats up water fast.
