Thank's a million guys for all the feed back and suggestions. This is what I did after listening to you. I went to Interstate battery and bought two 6 volt batteries, a heavy duty battery box, and the salesman made me a 2 awg jumper cable to jump from the neg. terminal on one battery to the positive terminal on the other. Total cost at that point about $350. Harbor Freight was running an ad for inverters. Originally I was going with a 2000 watt model from another company with PSW. After reading the posts here and the reviews elsewhere, I decided to go with a 750 watt MSW from Harbor Freight. The sale price plus the additional 20% off coupon set me back about $40 for the inverter. I set up the battery box and batteries in the pass through storage near the laundry shoot that has an access door on the steps to the bedroom. This set up is about as uncomplicated as it comes. After hooking the inverter to the batteries via the alligator clamps supplied, I plugged in a shop light and turned on the inverter. It worked. I then took an extension cord and ran the cord from the inverter through the laundry shoot, along the edge of the kitchen cabinets to the entertainment center. I plugged a six way circuit protector I use for the lap top into the extension cord. I then plugged the XBOX 360 and the 32" Vizio LCD Tv into the system. Both turned on and worked as if they had been plugged into a normal 115V source. I ran the game box and TV for 90 minutes and all was well. I then disconnected everything from the batteries and inside the 5'er and hooked up the battery charger to the batteries for the initial charge. I did not check the charge on the battery prior to using it and have no idea whether it came fully charged or not. My set up at this point is right at $400. If this works as I think it will, it won't be long before it pays for itself in saved propane use. At some point I thought I might try to figure out how to wire this inverter into the 5'er itself which would then send power to the entertainment center plug in's. Granted, this is a very crude set up but it worked. I figure later on if I need more power I will add two more golf cart batteries to the bank.
