For years I carried a trunk full of tools when out on the road and never had need for any kind of tool. Now I carry and adjustable jaw wrench,wire cutter, screwdriver with various bits, vice grips(the real thing made in DeWitt,Nebraska), small roll of gorilla tape, roll of wire,knife, red flag and whistle,small plastic tarp.Don't think I will ever use any of those as we are only driving about 3000 miles a year now.
