Thanks for the information. At this point it sounds like the easiest way to find out if we really want to Boone Dock is to pick up a second battery and one of those $100.00, 800 watt generator wonders from Harbor Freight.
I have a multi-stage Black and Decker charger and if I do not have to worry about a complete charge on the battery, the charger will provide 15 amps.
Therefore, a three or four hour charge on one battery while the other runs the TT should do us until we decide of we really want to Boone Dock for any length of time.
I have in the past disconnected the TT battery and run a set of jumpers to the TV and pumped some juice into it for twenty minutes or so to buy us an extra day. Crude but effective and when you are in the middle of an open field there are not to many other options.
