Wow - what a great thread. Lots of great information exchanged.
OP, I am in a similar situation as you I think. I do 3 or 4 day dry camping trips a few times each year. I have a TT with All LED lights. We use about 24 AHs per day.
I have a single 140W solar panel and no generator. About once a year (due to heavy shaded site) I just use my jumper cables to charge the TT batteries from the Truck alternator. For my use (2 hours per year) it is simpler than owning, operating and maintaining a generator.
During the hot summer time I only camp at electric sites so I can run my AC.
Anyway, this is what works for me right now.
