How much fuel is needed to generate 3 days worth of electricity assuming the A/C is used?
3-4 pounds per hour for the 2KW needed to keep a 13-14 KBTU A/C running. For the rest of the loads, it depends on how much power your lifestyle uses.
How many hours per day for A/C will depend on heat loads and what temperatures you are trying to maintain. There is a lot of variability in this, as you can use a lot more power trying to keep the interior of a RV at 68 F than you will use if you are comfortable with moving air at 80 F. If it is 100 F outside and you are in full sunlight, running AC continuously might not even get you down to 85 F. If it is 80 F outside and you are in full sunlight, you might cool down more by opening the windows and running the vent fans, because the A/C might not keep up with the full sunlight heat load even when running continuously.
