I am traveling 28hrs from just above you in NC... I really appreciate that list.I travel from the east coast to the west to hunt 4 or 5 times a year. The only time I usually fly is for spring bear. A lot of these trips are also solo.
Below are things I always have in/on the truck.
2 spare tires.
A good air compressor
4' piece of pipe if something gets real stubborn.
Thats regular truck stuff I can think of off the top of my head that goes on every trip. Obviously, thats stuff is more for the travel portion of the hunt then the actual hunt but for me its usually 25+hrs each way. I usually backpack in when I get there but I can't tell you how often Ive used alot of that stuff and I dont drive some old beat up truck. Stuff just happens and sometimes Im a long ways from anything. I also always have an inreach.
