Get yourself and your rig ready for the trip: Make sure both you and your vehicle are prepared for your next adventure.

Before you venture out on your offroading trip you need to make sure you are prepared for emergencies. Even if nothing happens to you or your vehicle, you might come across someone who needs help. Short of having your full-on bug-out-bag with you, you should at least have some basic emergency items. It might seem obvious to some, but you should get yourself a tool box with appropriate tools and leather gloves, good first aid kit, fire extinguisher, set of jumper cables, emergency blankets (stored in heavy plastic bag – both are useful), flashlight, tow strap and some extra water. I would also suggest a recovery strap, a military folding shovel, heavy duty garbage bags, and a hand crank self powered weather radio. These items are not expensive, but they just might save your day.

Another thing you should definitely do before you leave is to save the number to Arizona 4×4 Off Road Recovery in case you find yourself in need of recovery in the middle of nowhere. Their number is (602) 697-8306.
