Which Fuse is My Problem?

Dead truck battery this morning for no reason. After watching many YouTube videos it was determined that I had to check each fuse to see which circuit might be causing the problem. After 2 hours of checks I charged the battery started the truck and called it a day. I started thinking that this truck has not been run enough in the last 3 months to keep it charged... I guess I will find out if that theroy holds true :)
