Hi David, When adding that extra car battery, one can get a small unit called an isolator that keeps the batteries separate, so you can drain one and still start the car with the other. And if I was Trapper, out in the sticks, that is the what I would do for lots of power for very little expense. Using the rest of your ideas, of course. :O) Bob Noble www.sonic.net/bnoble ----- Original Message ----- From: "Emery, David" <demery@xxxxxxxxxxxxxxxxx> To: <pcductape@xxxxxxxxxxxxx> Sent: Tuesday, February 25, 2003 6:51 AM Subject: [pcductape] Re: Advice Needed | You have to look at power consumption (watts) and purchase an invertor that | has enough wattage to support.
