I will be carrying my towbar. Much cheeper to find a vehicle with a pintle hitch than pay big $$$ for the big tow truck!!!!
But really a good list would be common with the "Picking up your deuce" list.
Have basic fluids handy, DOT 5 Brake fluid, GL 1 or Equiv Gear oil, Antifreese, WD-40, a good water remover fuel suppiment, Greese gun, Motor oil
General spare parts, Headlights, marker lights, flashlight, fuel filters, Small collection of nuts/bolts, A few short pieces of verious sized heater and fuel tubeing, mechanics wire, electrical wire, Electrical tape,Tube patch kit, Troublesome parts related to your truck, and dare I say it ......Duct Tape.
General tools, A complete socket and wrench set, pliers, vice grips, a good jack, lug wrenches, a gladhand airline, a prybar.
Im shure Im leaving out something...... Whatever it is , it will be the item you need most!!
