Your brain, if God gave you one ... other than that, straps, basic tools (ratchet set, wrenches, etc...)... most of what you don't already have should be there in someone else's truck... if you have access to any spare tie rod adjusters, that's always a good idea... I'd call around to the local junk yards and see about those... a good spare... a hi-lift is nice, but again, someone else will probably have one if you don't... I think it came in pretty handy for Ivan (I think that's who it was) last year... don't forget your flashlight and extra water...
