Some of the things that I've seen come in handy with a sami multiple times are as follows.
* Come along
* Straps/cable/snatch blocks
*Correct sockets and wrenches to pull the drive shafts loose and put them back together.
(if you get airborn and run out of spline... hey, I'm just saying lol)
*Tools to pull motor mounts loose in the even of a roll over that leaves you with an engine sitting crooked with the fan jammed up into the shroud. (once again... I can neither confirm nor deny that this has happend to me twice)
*Air gauge and compressor to air back up after the trip. It seems like common sense, but I've seen it forgotten before.
*Duct tape, Bailing wire, zip ties, RTV, teflon tape, sticky velcro, 550 chord, and an LED headlamp
*extra quart of oil, and a jug of antifreeze (if your sami is anything like mine lol)
*box of granola bars and an unopened gallon of water in case of emergencies.
If you don't have any good points to tow from, you need to seriously consider putting a couple on before hitting the trails.
