Hey Chuck,
I like your planning, not my style but I admire it. I always do carry a jump box with a compressor this alows me to jump my own vehicle without hoping for someone to come by, it also allows me to fill a flat tire and plug it (always carry a plug kit). Like to carry cut stop powder for the dog and duck tape. For the hunting I like extra clothes an extra gun and ammo. Some power bars and water.
Thats about it.
