Looks pretty good, though I don't carry that many tools. When I had a Dana 35, I had axle shafts. The only thing worse than wheeling with a Dana 35 is not having spares when you break it. Friends don't mind helping, especially if you've got spares.

I'd add a chain and a tree-saver strap to the recovery list. A snatch block (pulley), too. I use all that stuff lots.

The most important "emergency gear" you can have with you is three or four other rigs (friends) on the trail with you. Even if you burn to the ground, you're friends won't leave you there. We've all heard horror stories. The common thread is that, no matter how many days it took, every one gets home.
