Hey, Mavrick,
think the only precaution you really have to have is a long rope for towing. Lol.
You can bring other items for little fixes, but with newer machines, breaking down really doesn't seem to happen much.
I'm sure others will chime in, but, my buddy's trip was pretty flawless and all had newer machines.
Alaski,
when we get this up and running, would be good to have you join us!
