Tackman,
There are some real good additions in your kit - some of which are kept in the truck, some which need to be added. The spare ziplocks are in the pack, along with 2 garbage bags. I added moist wipes to the truck the day AFTER the blackout. I don't carry a trifold in the truck, as when I pack the truck (aka, not everyday) - I put a full sized shovel. The "Pocket" mini kit is not waterproof OR in a ziplock, but there is an identical kit in a ziplock in the pack!

The whistle is on the list - I want to get a Mini Fox40, but have NOT been able to find one locally. I was able to find a full sized storm, but that is WAY too big.

Most of what is going to get added will go in the "truck" layer, unless it's small. You see, I have to CARRY that backpack every day (I live in NYC, and take the train and subway). At 47 lbs with the stuff I need "for work", it's getting close to the max I'll carry as an EDC

I really need to list out the "truck" layer one day. Part of my reason for the photos is that I've printed my web page, and use it as a checklist! I have to do it for the truck too
