EDIT: May as well list my stuff too; you should all feel free to tell me if I'm being stupid:
25' 20,000 pound recovery strap with loops on both ends.
15' chain
2-ton come-along
Receiver shackle bracket with 2 3/4" shackles
8' nylon tow rope with hooks that came with a roadside emergency kit (can't see me using this for much of anything)
You can never have too much recovery gear.
