A few answers for you are in your other thread. As was posted over there, an energy audit of your proposed use is the first step for figuring battery capacity, inverter size, and what you'll need for a charger.
I'd suggest you think a bit about the MSW vs. TS inverter situation. The price spread is not that much anymore and when modern electronics and their charging systems need to be powered, you may wish for that TS inverter.
There are available, also, charger inverters that have built in transfer switches. The entry price is high but it does make everything a bit more seamless.
On a side note: What are you hunting out of that camp? I'm a hunter, too.
