No audit info (yet) but here are some suggestions
I just bought a 2005 AF 860. Assuming they are generally using the same equipment, I am in the midst of finding out how much energy I need as well. Other than the heater and inverter items (microwave, tv, etc), you should be easily run the lights, pump, & fans off 200W solar. you can probably run your fridge as well, but note I think if you run it in auto mode, it will default to propane first.
Another suggestion is to buy a higher end solar panel controller, some models will give you amps in and out (if you wire them properly).
Good luck and be sure to post what you find!
