Well first off, since winch is a last resort for self recovery... yes I have one, yes I have winched myself out exactly 1 time in the past 30 years... and yes I have gotten stuck a lot more than that...
The best recovery tool is knowledge gained from experience... how do you gain experience? Go get stuck then get unstuck... then repeat. Once you get this down and you realize that getting stuck sucks... (literally)... you will be less apt to go places that leave you stranded...
so I know that’s not the advise you wanted to hear..and you are looking to the physical tools...
You are located in Oregon... traveling Forest Service and BLM roads and trail systems require a load out for the majority of them. The basic list is small, but not having them could result in a fine at minimum...
NFS required Fire Safety Tools:
Axe
Shovel
1 gallon of water
5# Class AB Fire extinguisher.
I bring this up because all of these could be used in a self (or buddy) recovery operation.
Axe can be used to chop dead Wood to make a lever to lift, push, or slide the vhehicle. Can make blocks of wood to make a stair case to drive out of a hole, and so many other things.
Shovel can be used to dig out the frame and low hanging parts on the rig... it can be used as a traction aid, the shovel is my 90% go to tool.
Fire extinguisher puts out the fire you started by spinning your tires (just kidding... or am I watch cyoteworks on YouTube to see his nice Jeep burn to the ground)
Water- use it to rehydrate while working.
Ok the bare essentials are done and out of the way...
You need a “tree saver” don’t anchor to a tree without one... I recommend at least an 8’ one.
Kinetic recovery rope at 25’ long
And that is really all you need... your traction boards are nice, but I can only think of a couple of times where I was like “yea a board or something would really be great here”.... I fact I don’t own and don’t plan on ever owning traction boards... ok I lied... I want a set to help spread the load of my jack when I pop my tire off the head in the sand... or have to jack for what ever reason in the snow. But that’s it, not as an actual traction aid...
