Wow, lots of good (and contradictory) information, on this page and the previous.
People here can be rather technical. This why I find this section of forum useful. Read the last post by Landyacht, it's easy to see why some posts contradict each other - too many variables.

As for my electricity use: I don't heat food, make coffee, run a furnace or fridge, etc., on batteries. I use tent camping equipment for lights, food, etc.
Sounds like prime candidate for solar.
Without a furnace your daily draw should be 25-40 AH a day. This includes DC circuit of propane fridge and occasional laptop charging.
250W solar will harvest that much in AZ in December on a clear day. On a dark winter day it will harvest 10-20 AH a day, depending on how dark.
At 40 AH daily draw, with 2*100AH battery, you can store enough energy to last 3-4 dark days with partial solar charging and without running your engine, so the battery will be down to 50% on day 4. Or - unlimited stay with running your engine on those dark days for 20-30 minutes, and no engine running on clear days. Don't know if in places like QZ there can be 4 dark days in row, in Baja this doesn't happen.
2*100 AH battery can be either 2*6V flooded GC mounted outside, or 2*100 AH AGM mounted inside.
