Some here are looking at using a hybred vehicle as a power source for their RV. The soon to be developed plug in hybrid F150 is being advertized as a workplace generator that can power an RV as well. I believe a Pris could be used to generate power as cheaply as most small generators. Even plug in Electic Vehicles that can access grid power if you could tap into their large battery packs would be useful for power and power storage. You could drive say 10 miles to town charge up on grid power while at work then drive 10 miles home plug into your RV and charge up your house batteries. It is something to look at as there is a video where an older Pris with a bad battery pack purchased for $1,500 gets a rebuilt battery pack with a three year warenty for $1,500 and a few hours DIY labor becomes a daily driver valued at $4,000. A good generator or solar system would come close to costing as much for an RV and not transport you around cheaply as the Pris would. You might even be able to charge house batteries for the RV with the Pris or at least supplement a smaller cheaper solar system and save money. I hope some who have tried or are doing this will post as I am courious as well.
