    Your truck has a number of key systems that play a role off-road. It's important to understand them, and what they do.
    Traction Control: Most modern 4x4 vehicles will have some level of traction control. Depending on what conditions the vehicle was designed to conquer, it could have a simple on/off setting, or a complex system with multiple settings programmed for different traction situations. No matter the system, traction control uses either the brakes and/or the 4x4 mechanicals to limit wheel slip and ensuring torque is being transferred from the tire to the trail. "Traction control tells the onboard computer how to monitor wheel spin and it will brake accordingly to keep the vehicle moving forward," adds Clay Croft, Creator and Expedition Leader of Expedition Overland. Since there are so many kinds of traction control systems, we encourage you to read up on yours and its many settings in your owner's manual.
    4WD High vs. 4WD Low: Low and High speeds refer to the gearing of your transfer case. 4WD High is what you drive around in day to day. It allows for better top-end speed but lower torque to the wheels when stopped. When you go to 4WD Low, you have more torque on low-end speeds, but your top speed is maxed out pretty quickly. "In short: when you need a lot of low-end power at low speeds on the trail, go to 4WD Low," Croft says. "When you need to travel fast and keep momentum, you need to be in 4WD High."
    Locking Differentials: A locking differential essentially locks the turning of the left and right wheel together. In normal on-road driving, the wheel on the inside of a corner turns more slowly, as it travels less distance than the outside. In this instance, you'd want the wheels to turn at different speeds. In an all-wheel-drive system, the computer is constantly making adjustments, shifting power to where it's needed most. On the trail, however, this inconsistent speed between the left and right sides can lead to a loss of traction, as the power will go to the wheel with the least resistance -- often the wheel that's slipping or not getting traction. That's why you want the ability to go full-time 4x4. Doing this forces both wheels to spin at the same rate, ensuring the power remains with the wheel with the most traction. In the old days you had to get out and manually lock the hubs, but most new 4x4s allow you to lock the differentials using just a button push. "If you can buy a vehicle with a factory locker in it, you are ahead of the game as a novice getting into this world," said Croft. "Being able to get into a vehicle that has a locking differential in it is a huge plus for the off-road capability of that vehicle."

    2. Do You Need Any Special Equipment?
    Tires: Getting a good set of tires to match the most common types of surfaces and terrain that you're going to encounter is essential. Tires are what ensure traction between your vehicle and the terrain. Their importance cannot be overstated. No matter how stout your rig, if it doesn't have good tires, it'll be feckless, and mud tires are different than tires for sand and rock. We suggest you go to a local tire shop and talk to some experts.
    Suspension: Don't make the common mistake of getting a cheap body lift kit. Believe it or not, a fundamental element to off-road vehicle reliability is the shock absorber; it's the thing that takes all the abuse of the trail and helps to not translate it to the vehicle or driver. Think of suspension as one of your biggest foundational elements to building your vehicle, because, as you go to add new things - a drawer system for organization, for example, or a rooftop tent - you'll burden the suspension even more. And the more your suspension can handle, the easier your trek will be.
    Bumpers: Sometimes referred to as bull bars, aftermarket front bumpers protect the front of your vehicle from rock, tree, brush, and animal strikes, as well as other unavoidable trail obstacles. Off-roaders might also consider a back bumper, depending on what sort of driving you're doing. A lot of aftermarket bumpers allow you to relocate the spare tire from underneath the vehicle and put it on the back of the vehicle, which, in the event of having a flat tire or being stuck in the mud hole and needing to swap that tire out, ensures it's not buried under your vehicle when you need it.
    Maxtrax: Designed by Australian Brad McCarthy, this is a traction device that goes under your wheels and allows you to crawl out of a hole by regaining traction and momentum. When you lose either traction or momentum, you're more than likely going to get or lose control. And when you start to lose traction, often you can't regain the momentum essential to getting your vehicle going again. Maxtrax help you regain traction, to get up out of whatever you're stuck in, and give you momentum back.
