Before heading out on any adventure, your vehicle should be in sound operating condition. If it has been sitting a while since your last excursion, run down this list and inspect each component. Fluids should be in good condition, unburnt, and with little / no oxidation. Rubber components and electrical cables should be free from cracks or splits. Areas under pressure such as brake, fuel, and clutch lines should be checked for leakage especially around fittings. Check the tires for correct pressure and look for dry-rot. Give the engine a fresh splash of oil and a new filter. Change the air cleaner. Those of you with automatics should also give some love to your transmission filter.

Always travel in groups of two or more vehicles. Each vehicle should have a basic tool kit, recovery kit, and first aid kit. Be sure to alert someone back home of where you will be going and when you expect to return.

Required Equipment:

Vehicles must be highway-legal. This includes functioning lights and blinkers, seat belts, fenders, and registered license plate.

  • Type ABC Fire extinguisher, easily accessed
  • Tow strap, 20’ minimum with no hooks or brackets
  • Tow points front and rear
  • Full Sized spare, matching lug wrench
  • Bottle jack with 12” square base (a slab of wood will work)

Every vehicle, whether a grocery runner just out for a scenic drive or a hard-core rig crawling over rocks should have the basics above covered. You never know when you will need to fix a flat, perform a self-recovery, or help a less prepared wheeler down on their luck. If you are traveling in a group having the basics covered ensures that you will not be a liability to others, and that you will always be ready to lend a hand to a traveler in need.
