Re: Tool kit for the road
8 and 10mm wrenches, phillips and flat screwdrivers, small visegrips, small crescent wrench, allen key set, patch kit, portable hand pump, spare tube, spare sparkplug, flashlight, cellphone.
_On extra long trips I also carry a ratchet and 14mm socket for head bolts)
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
