Shame, that poor oak, sounds like it was a beautiful tree. At least it's going to be used nicely and not go to waste. Around here they fell trees and just leave them to rot, quite sad really.
I think smaller storage containers is always wise because then if something does happen, you might not lose your entire cache of goods, you might only lose some of it (to spoiling or pests for example), although looks like you are taking everything into account. I wish I was as organized as you are. I'll get there eventually.
Everyone preps at a different rate, so you're doing fine! Just keep working at it, you'll get there....
