Always a pocketknife…. I’m always close to my rig so there is plenty of stuff in there….. one thing I learned along time ago was water. Here in the summer it can be non-existent. Every vehicle has at least a gallon if not 2-3. A basic tool kit and jumper cables but mostly water.
If you are broke down anywhere….. even if you can call someone it may be an hour or 2 before someone can reach you. Heat exhaustion/Stress is real dangerous.
