To run your AC (and everything else, although they're really negligable) that long, you're going to need 37 100w solar panels. That's probably not going to fit on your bus, and by the sounds of it, it definitely won't fit your budget. Also, that 100w rating assumes that these panels are at a 90 degree angle to the sun. So, you'll need to tilt the panels. That also assumes you don't have losses from a crappy PWM solar controller. So, you're going to need MPPT controllers, which are expensive ($550 and way up). And you'll run four 6v Trojan T-105REs down to damaging levels in just two hours.
So, you're best bet is to either use your bus' engine as a generator, in which case I suggest an alternator to battery charger (These get much more power out of your alternator than a simple isolator will. They are well worth the money.) or buying a generator tied to a charge controller (You'll want/need the charge controller if you plan on plugging in anywhere anyway). The generator is by far more efficient (quieter and smells better), but you'll have to find a place for it, and store gasoline for it. It's more expensive up front, but cheaper in the long run.
Another tip would be to get a smaller AC unit. I'm in Texas where the weather is just as hot, if not as humid, and I'm running two 6,000btu window units. That way I can run one when I need to conserve power, and two when I can plug into "shore power" at a camp site or friend's house. New window units are cheap. And running just one of those will only cost you 7kW for the day instead of the astronomical 26kW you're talking about. I think my whole central air system at home uses less than 26kw a day, and I like it COLD!
With my setup that I'm building currently, I'm going to run the alternator to battery charger for when I'm driving (free power), 4x 250W solar panels on tilting racks, a MidNite Solar Classic 200 MPPT solar controller, a 3000w inverter/charge controller combo, 8x Trojan T-105REs, and a 30A shore power plug. I expect my total setup to cost me just under $5k. I also intend to add a second set of solar panels and solar controller next year to get another 1kW of solar up to need to run the bus engine less often.
