While the pick-up truck was commonly used for business and recreation in America, it was a while before its role from workhorse only changed in other countries. In part, it was because the earlier trucks were not really comfortable or designed for personal enjoyment. And in countries like Malaysia, licensing regulations also restricted their use by private individuals not doing business (the law changed in the late 1990s).
Then, from the 1990s, along with the SUV wave, many automakers began to also make their trucks more ‘civilised’ with features and safety similar to passenger cars. The modern trucks are still just as capable, unlike many modern SUVs which have moderate capability and are more for use in the ‘urban jungle’.
Trucks can still go off-road and over rough terrain, and some have advanced systems to help the driver in difficult situations and also to improve safety. The Isuzu D-MAX is a fine example of the modern truck which has all the comforts of a passenger car and off-road capabilities that have been demonstrated in events like the Borneo Safari.
Many people who buy a truck are likely to also have what is called an ‘active lifestyle’, involving outdoor activities like camping. This means travelling into the jungle or distant places far off the highway where there are no proper roads. Most trucks can handle rough ground and with the D-MAX, there are also active systems that help get out of trouble (eg a differential lock for extra traction).

For those with moderate experience, Isuzu UK offers tips for off-road driving, covering preparation, driving techniques, recovery tips, and post-drive vehicle maintenance to ensure a smooth and safe adventure.
The tips are compiled into a guide which focusses on driving in mud, which is common in Malaysia too. It emphasises key practices such as maintaining steady momentum, using the rear differential lock, and thorough cleaning to prevent damage after mud driving and ensure safety on the next trip.
Pack for mud
Before heading out, pack a recovery kit with essentials like a tow strap, shovel, traction aids (recovery boards), gloves, and an air compressor in case of tyre pressure adjustments.
Check all tyres
The standard tyres are usually more for highway driving with moderate off-road capability. So if you are venturing into areas which will be muddy, it is better to switch to all-terrain tyres to improve grip. These tyres have larger tread blocks to ‘bite’ into soft ground for better grip, and they also disperse mud rather than have it clogging up and turning the tyres into ‘slicks’ like bald tyres.
Use 4WD mode
Switch to 4H or 4L when conditions make it necessary. 4H is suited for general muddy conditions, while 4L offers more torque for deeper or thicker mud. So it is important to look at the conditions ahead and understand what sort of surface you will be driving over.
Maintain steady momentum
Keep a consistent speed without sudden acceleration or braking. A smooth, steady pace helps avoid wheel spin and sinking. Going fast is not what off-road driving is all about and can sometimes even get you into trouble.
Keep wheels straight
Keep your wheels pointed straight ahead as much as possible. Turning in thick mud increases resistance and the risk of getting stuck. However, when stuck in mud, turning the wheels left and right may also help as they can grip into the sides of ruts.
Use rear differential lock
Activate the rear differential lock when necessary, especially in deep mud or inclines. This ensures both rear wheels move together, improving traction and helping you power through. Activation should be before you actually get into the deep mud as doing so after you are in might not be so helpful then.
Avoid over-revving
For the less experienced drivers, there may be an inclination to add power when it difficult situations, hoping to drive out quickly. But that can spin the wheels instead as they are not gripping properly. That will cause the vehicle to sink deeper into the mud. If you feel a loss of traction or wheelspin, ease off on the power first and then try to regain grip.
If you get stuck
If you get stuck, don’t panic. Gently rock the vehicle back and forth by alternating between forward and reverse gears. Using traction boards or digging the mud away from the tyres which can also help.
Post-adventure clean-up:
After the adventure, clean the vehicle thoroughly. While driving home, much of the mud will come off but there will still be some stuck on the undercarriage, in the wheel wells and brakes, Spray the mud off to avoid potential long-term damage. Besides, you will probably use the truck to go to work on Monday, so have it looking good!
Inspect for damage
Check for any damage to the tyres, suspension, and undercarriage. Pay particular attention to steering and braking systems to ensure there are no issues.
