The many burnt-out vehicles abandoned in remote parts all over Africa are grim testimony to the fact that fire is a major risk when overlanding. The culprits are a combination of high ambient temperatures and tall grass, plus heat from the engine and (even more often) from the exhaust. How does one deal with this? The fact is that even green, wet grass dries out very quickly when exposed to the high heat and ventilation of the exhaust areas under a vehicle. This happens within minutes, not hours. In certain circumstances, you may have to stop every 10 minutes to…

The Waeco CFX-65 fridge-freezer we have been using since early 2013 has now been rebranded a Dometic, in line with the Swedish company’s brand-consolidation exercise. It was always built by them, so this is just a name-change for this fridge which needs no introduction as the unsung hero of all our local trips. Whether it’s working at max capacity in 40 degree heat or sitting turned on in an office for months at a time, the old beast has its work cut out. And it hasn’t missed a beat. As Grant Spolander put it in his 2013 review of this…

Back in the early 1980s, BF Goodrich introduced an unconventional tyre that would forever change the way we thought about off-road traction. They called it the T/A Mud-Terrain: “T/A” borrowed from their successful line of street-performance offerings, and the rest for the type of terrain it would call home. It was the first such tyre with an aggressive tread design, deep voids, and radial construction. The impact was such that, in the following years, nearly every tyre manufacturer in the genre would introduce a variant of BFG’s original design. In 1984, the company rocked the four-wheel drive community with a…

Let’s face it, Z-folds work a treat for sleeping, but they are hellish bulky. When you pack for a family of five or more, chances are that the mattresses take up half the available space. Most people have experimented with the blow-up balloon type, which pack lekker small and flat, but it doesn’t take long before everyone’s had enough of broken or forgotten pumps and that sinking feeling when a mattress is punctured. It’s only a matter of time. Somewhere in the middle of the bulk versus reliability debate is the self-inflating mattress. For car-camping purposes, we’re not talking about…

Water is the elixir of life and a priority on any overland journey. We need at least two litres per day just for drinking, before we can even consider washing grime off our skin, brushing our teeth or tackling the dirty dishes. Although some tannins in water have a nasty taste, and some may discolour surfaces, water is also the perfect breeding ground for a wide variety of bacteria, parasites and viruses that can ruin a trip − or even end your life. But, for the well-equipped overlander, there are many filtration options, each with its own pros, cons and…

Fire. It’s a vital component of any overlanding journey. Internal combustion powers your 4×4; and more often than not, fire cooks your meals out in the wilderness. On the other hand, fire can be the cause of your journey’s untimely end. Unfortunately, while we are all too eager to stock up on gas bottles, jerry cans and firewood, we often overlook the absolute necessity of having fire extinguishers. Fire extinguishers are not too expensive to purchase and are widely available in many retail outlets. It is also simple enough to mount a fire extinguisher in your cab, or to stash…

Good news for our Mazda BT-50 long-termer is that it has just been fitted with a set of Dunlop’s Grandtrek AT3G tyres. We fitted a set of LT 265/65 R17 tyres which have a load rating of 120 (1400kg per tyre), and an “R” speed rating (170km/h). Pricing per tyre at this stage should be around R3000, ex Vat and fitment. Why would we change tyres? Simple, really. The AT3G, unlike a number of other all-terrain tyres on the market, has a three-ply sidewall design; and from the get-go, it looks to be the business as aftermarket fitment for tough…

You want tyres fit for the bush, which are also comfortable on tar? Yup, you have entered the realm of All-Terrain Rubber which must grip and grind its way over a variety of surfaces. But which brand is best? The SA4x4 team amassed 17 sets of AT tyres for the biggest local tyre-showdown ever… The tyres The tyre market in South Africa is rapidly expanding – in volume as well as in brand diversity. World-renowned manufacturers such as Bridgestone, Goodyear, Continental (General) and Sumitomo (Dunlop) have facilities here, and a plethora of brands is imported through companies like TiAuto, SA…

Chris Collard shares his three decades of backcountry breakdowns, and the tools and equipment needed to get you (and your vehicle) home alive. For Chris’ full insights, grab the December 2017 edition of SA4X4.If we sat around a campfire spinning yarns about our early exploits into the backcountry, my guess is that the memories, regardless of the details, have been filtered into blissful adventures. They were most likely simple affairs with a full complement of necessities: a cooler of coldies, sleeping bags, and camp chairs. I recall the first trip in my ’82 Hilux. My buddy Rich Currie and I…
