PREPARING FOR THE GREAT TREK - POINTS TO PONDER
On an extended overland trip, THE major concern is the availability of spares. So hereís a very rough guide, based on observation of the spares and repairs front in the countries to our north and west.
Land Rover 110, Discoveries, new Land Cruisers and Pajeros are the vehicles of choice of the wealthy aid workers and diplomats, so limited spares are usually available, particularly if there is a UN workshop in the vicinity.
Namibia, Botswana and Malawi : Land Rovers and Toyotas dominate, spares and repairs are relatively easy to come by for all makes - and can be freighted in from SA if necessary.
Zimbabwe and Zambia: Land Rovers and Toyotas dominate but spares are tough to find other than for old model Land Rovers. Even 110 spares are scarce.
Mozambique: Take all your own spares. Spanish LR Santanas are common.
Tanzania: Relatively cheap spares for old Landies are available even in the smaller towns. 110 spares are common in main centres. Labour is cheap and good.
Kenya: Spares are available for all models of Land Rover. Labour is cheap and good.
Uganda and Ethiopia: Land Rovers and Land Cruisers dominate - buy spares in Kenya.
North and West Africa: Toyota and Land Rovers dominate. Spares are available in most major centres, at a price.
Zaire: Spares are virtually unobtainable for all makes.
Be Wary of over engineered extras like power steering, automatic transmission and air conditioning - they all add weight, are more susceptible to failure than simple systems; and if you are travelling rough, delicate electronics and intricate fuel delivery systems can go disastrously wrong.
Diesel engines are more difficult to service, but a simple course will teach you the basics. The tricky bits come with injector and fuel problems. Diesel fuel is often dramatically cheaper than petrol, is not a fire hazard and gives better consumption and range - a very important consideration for remote expeditions. Diesels use electrical power for starting only (petrol engines have a constant electrical circuit in place), so you can wade deeper, crossing bonnet high mud and water holes with fewer problems.
Most African petrol is of very low quality; if your vehicle runs ragged on regular at sea level, you will have problems. Engines with compression ratios of higher than 8,5:1 can be seriously damaged by prolonged use of bad fuel. The alternative is to carry a large supply of octane-boosting additives. We used these to get over mountain passes of over 3 000 metres in Ethiopia, when our Landy couldnít move up anymore, not even in low range reverse.
