All fluids, belts, tool set, jumper cables, fire extinguisher, toe strap, tow chains, air compressor, rope, flashlight, flares, various electrical stuff and a fifth of JD!

 

You guys crack me up. I don't have a tree buisness, I had to log a large area on my land once so I never stopped carrying them around.

 

Fluids, Breaker bar and sockets, short piece of wire (so I can prime / turn it over from under the hood), can of ether (never used - just in case), dual 48" Hi-Lift jacks, full set of recovery gear, shovel, flashlights, VHF radio and Sat phone.
Bent piece of wire in the bed so I can push the "unlock" button through the vent window seal (due to past bad experience).

 

OK that's sounds reasonable now. You never know when around the next bend you might find a downed tree blocking the road.

 

oh i also have a 10 ton bottle jack, a chain fall, several chains and straps, belts, hoses fluids, zip ties, baleing wire and duct tape...pretty much anything i could possibly to fix, break, lift lower pull, push or otherwise relocate a truck or tractor
