I carry everything on my back in a backpack. misc bolts, washers, nuts, tie wraps, tie wire, hose clamps, 8,10,12,14,17mm ratchet wrenches and sockets, large channel locks, butt splices, electrical tape, spark plugs, tire plugs, bike pump, metric allens. I think thats it. Alot of times if I go out with my dad,. there is a parade of 4x4`s with him and I put my bag on one of their bikes with the beer and radios.
