Your recommendations on a 12hr drive kit

Your recommendations on a 12hr drive kit from Southern Cal to Northern Cal?
hey guys this is my second post on this forum, A bit about me I’m 25 with a son & wife, Work for the county and work at my local indoor shooting range, I would carry my glock 19 for conceal if this state wasn’t as strict.

I’m driving to the beautiful city of San Francisco, The drive take 6hr.
I wanted some recommendations on 1st Aid gear that I can take along, electronics that may come in handy and any misc. Again I regret that California dose not have any open carry or CCW’s.
