I understand your background, that said I find it easier to reserve a site with electric, the added cost is so small that by the time you spend money on the gadgets and two generators, the labor, I'll be enjoying my air pluged in to a pole on my site. I know you had a generator lying around but you still bought it!
I do find my Honda quite capable and very quiet, just choose to leave it home most of the time.
I camp 35 - 40 nights a summer and have yet to camp in an area without electric.
Camp more work less works for me.
Maybe someday I'll think differently and appreciate your research but for now I'd rather plug in and camp. I do understand those on solar in National Parks but in NE Ohio we have electric.
