For those that wanted to know, here’s my disaster deployment stuff ready to go.

Backpack: 511Tactical RUSH 24-hour.
Rollerboard: Travel Pro MaxLite-3
Pelican case(s): 1510 Pelican cases (both admissible as carry on luggage on any domestic airline)
Large rolling duffel: Columbia Storm Chaser. Normally, I put the boots in the outside boot pocket of the large duffel, but I wanted to give you some size context.
Hope this helps out.
