The hybrid version doesn't need to be plugged in to charge it. Charges itself with the onboard gas engine. I know from past experience reading other forums that most folks that are into this lifestyle are very much against purchasing anything new. To me it's a matter of usage. If I were going to live in one city and not move the vehicle very much then I'd want the ability to stand up with a little elbow room. Could make do with a regular van but feel I'd last longer as a vandweller with a little extra space. As a retiree however I'd want to travel. As I would have time on my hands I could set up a camp in free camping areas using a good tent that I could back the vehicle up to. So a car for sleeping would be fine. But that vehicle that I'd use to live in a city would eat me alive on fuel costs. Yes, that new car price would pay for alot of gas with a used van. But that's why I'd buy a Prius if I were traveling. I'd make up over the life of the Prius much of the price of the car with fuel savings. And the Prius has proven to be one of the most reliable vehicles available today, important if traveling extensively. So yeah, I'd take the hit financially to buy a Prius outright. Am I rich? No, my company terminated our pension plan in 2008 and replaced it with a "cash balance plan". I'll receive a lump sum at 55 that'll cover the cost of the car. And what I accrued on the traditional plan before it was terminated will provide enough income to get by living cheaply. Am I lucky to have that? Perhaps, but I worked hard for a very long time for a bunch of BSers to get it. Besides the fuel savings and reliability, the Prius runs it's air conditioner off it's large battery. The engine kicks on to charge the battery as needed. This will allow alot of freedom to travel to wherever you like instead of always seeking out mild weather locations in the summer. If you want to be on the beach on the hot Gulf coast the Prius will allow you to sleep in comfort. You can do the same thing with a generator and a window a/c in a van but then you'd have to worry about the generator walking in the middle of the night, plus the high cost of driving to the beach. Sorry for rambling, very sold on the Prius, wouldn't try fulltime traveling without one as I can't afford the upfront costs of a decent RV and they are way too expensive to travel with on my budget.
