Enough Solar for conservative boondocking?

One more example - I dry camped (can't hardly call Quartzsite boondocking) in an Escape 17 all winter, the longest 91 days in a row. LED lighting, 195 watts of solar on the roof & a 160 watt portable. 2 6V 232 amp hour batteries. I usually make a pot of drip coffee each morning, sometimes an electric toaster, run the furnace some nights, and use a power hungry laptop, charge camera & phone batteries, a Cell phone amplifier, rare microwave use, etc. Generally, between 40 - 50 amp hours per day. I don't carry a generator.

Have moved to a Escape 21 with 320 watts of solar on the roof & tilting panels, which provided all I needed last winter.
