Solar crunch time! Please review my plan.
I would like begin my first post with a big thank you to all who have shared their knowledge and experience on this forum. Without that, I probably wouldn't be entering the solar jungle! I hope yo...

grizzzman - your guess is quite good. And over at Northern Arizona we have a couple of similar snarks. Disagree (as in say something nice about LFP) and you are off the island. It is not worth the effort to get involved.
We are currently mootchdocking (a nice portmanteau of mootching and boondocking) at older son's place at 7800' in mountains of northern NM. He is entirely off-grid, he and grandson built a pad for us with a sewer trap, and he now has a good well (solar powered). Solar insolation is great as we have had up to 1400 W to controller (TriStar MPPT-45) and 8100 W-hrs harvest in one day (we don't usually use that much but I ran the water heater on AC all day to see what might happen and the solar kept up with it - and the fridge).They have two great cats, three great dogs, one amusing semi-feral Peahen, 10 curious Barred Rock chickens (do not leave door of RV open) and two cranky Llamas. We had planned trip to Newfoundland via the Trans-Labrador and ferry from Blanc Sablon but Elaine needs knee surgery this summer.
Pianotuna- It is still a lot heavier. I just googled around a bit and I came up with 72# per 100 amp-hours and I was going with 50% SOC which would be 144# per 100 usable amp-hours. Your calculations have it about 3 times as heavy as opposed to 4 times. My knowledge of LFP is anecdotal from our experience and discussing with others.
