who dry camps with residential fridge?

You have more than adequate means for the task.

485 AH total bank is 240 AH usable energy. It will support the fridge and minor loads for 2 days with no charging. In AZ solar will contribute at least some charging, and you said your dry camping will be only 3-4 days.

At this point, your energy budget is a no problem already.

400W solar in summer will harvest "enough" or "almost enough" to run everything including fridge and not including A/C. Doesn't matter if the solar will harvest enough or not, because your battery will provide about a half of needed energy for 3-4 days.

In the end, with 5.5K generator that in 100F weather you will surely have to run because of A/C, I don't know what the heck you're worried about :)...

Wind turbine looks like an excess. Given the location and duration of trip, it will likely be less efficient energy source than solar, and any close neighbors will hate the sound. You might not like it too.

Sorry for being cranky, must be the heat.

Wind Energy, stand alone kit.....Drool, thats what i want, not solar. Patience is all i need.

The sticking point with wind power is that you need constant wind, a decent prop size, and the correct efficiency of generator to make it produce any usable power. I'd bet that the 100amp alternator should have a 7' diameter prop and unless some special gearing or pulley sizing is used, there won't be more than 5-10 amps produced. I mess with this stuff, occasionally.

I'd be very interested to hear how the wind turbine works out for you!

You should be golden. I run a 120V fridge with 235W of solar and 300AH of capacity. If the sun shines, I have no worries.
