Vehicle Prep Checklist

Most bad days on the trail start in the parking lot. A 20-minute check before you leave can save you a tow bill and a long walk.

Tires and wheels

• Check tread and sidewalls for cuts, bulges and plugs.
• Carry a full-size spare, a jack that works off-road, a lug wrench and a tire plug kit.
• Air down at the trailhead for traction and a smoother ride. Many drivers run 15 to 20 psi on slickrock, but follow your tire and wheel maker's guidance.
• Bring a compressor so you can air back up before the highway.

Under the hood

• Top off oil, coolant, brake fluid and power steering fluid.
• Look for leaks, cracked hoses and loose belts.
• Check that the battery terminals are clean and tight.

Underneath

• Check steering parts, U-joints and CV boots for play or tears.
• Make sure skid plates and rock sliders are tight.
• Confirm you have rated recovery points front and rear. Tie-down loops and tow balls are not recovery points.

In the rig

• Full tank of fuel. Stations are in town, not on the trail.
• At least a gallon of water per person per day, plus extra.
• First aid kit, fire extinguisher, basic tools, gloves and a headlamp.
• Recovery gear: kinetic rope or strap, soft shackles and traction boards.
• Strap everything down. Loose gear becomes dangerous on steep climbs.
