A Koolatron P-65 draws 4.5 Amps. If you use it 12 hours a day, that's 50 AH a day. I found one Wilson amp that uses 3 Amp at 6 Volts, assuming you'll need to use a 115 VAC to 6 volt brick of some kind you're probably looking at 35AH day (using a small inverter, 35 is probably about right, using a 12 to 6 VDC converter, probably a good bit less). If you plan to use another 15-20 AH daily (LED lights 5 hr./day, charge couple of cell phones) you're looking at 105 AH per day.
As a SWAG; I think you're looking at about 250 to 300 watts of solar, a 20 Amp MPP controller, and a minimum of a pair of GC batteries (4 being better). I think I'd throw in a 1000 watt gen and a good charger to keep you alive on cloudy days.
