Suggestions on food kits make sure each kit has some of everything. Having one with all X means if it gets lost damaged you have zero of x.
First aid kits. Your I fak which should be every day carry item should be able to limp you through same amount of time as your bob. Any less makes you vulnerable, this is something our group debated long time, we settled that you ifak bob has to contain items to keep you going for up to 2 days no sleep on the run from others.

Having a bathroom for bathing and handicap/invalid use if you can afford it is a big bonus. We recently had a drill of of med facilities and found a few areas which needed improvement.

Bathrooms became issue fast both using and cleaning.
