It sounds to me like you've got all travel and home possibilities covered.

My home has 2 FAK's: 1 latex and trauma and 1 non latex and minor day to day cuts and scrapes capability. My truck has a large FAK for trauma and burns and 2 smaller FAKS (GHB's). My van has 2 minor Faks (BoB's). The camper has a large industrial size FAK.

Always use your buddy's FAK on his injuries, save your FAK/Supplies for your own injuries.

I think you're providing your friend with their own FAK's is extremely considerate and meaningful gift that will be appreciated and treasured.
