I see a lot of good ideas up there, but don't go crazy.

Do not go alone the 1st time or 2 until you get a feel for it. See what the other guys bring to get a feel for it.

A good rope or tow strap with a cum-a-long can do wonders 

Oh yea, dont forget a smoking hot co-pilot that does not mind getting muddy

They help keep the seat clean.

Yeah the smoking hot co pilot is a good one! 
I'm one to talk about trail prep, I've had so much in the way of spares and tools packed into my tracker I had to remove the back seat!  My damn tool bag weighs almost 100lbs! When I went out west I packed so many spare parts I coulda had a garage sale on the trail. I still bring the tools, straps, and basic spares, but leave the axles, cv's, spare turbo parts, hubs, and all the other stuff packed in the spares case back in the shop. Until I go back out west that is. 

Bentparts your a funny dude... 

Most of what I listed is either preventative stuff or common carry items... Heck my toolbox is with me always. (Backseat removed and a perminant 2'x2'x2' drop front tool box sits in it's place.)

Shucks for that matter as long as yer confident in yer ride & friends ya can tag along... If the going gets too ruff park and ride. There is usually a buddy with an open seat cause the waitin game for a good lookin passenger can be a loooooong time....
