I usually think of the things I might need to do on the trail or campsite and see what it takes..like belt changes,axle swaps, tie rod change-outs, ect. With a CFM you never really know but its a safe bet to have some end wrenches-10,13,15,17mm, some vice grips, channel locks, some screwdrivers and a push-pin tool, plug wrench, a 3/8s ratchet with some basic sockets and at least one short extension. some zip ties, small roll of bailing wire. The rest just play it by ear as needed. One thing never to hit the trail without is a tow strap.
