I 'm a cautious person, so will always overestimate fuel usage to a "worst case scenario" .
My vehicle has 175 Litre's in total (not that massive really)... and i would calculate worst case figures at around 5.5km/l just to be safe (even in Low range 1st working hard at altitude) wont be worse than that ever.... has never been that low ever.
Folks have a Toyota D4D 2.5D 4x4 DC. - Dad gets between 12km and 14km/L - its an extremely efficient motor (granted, once it has a load its gonna kak a bit), but even then reporting figures of no less than 10km/l. at a 80Lt tank (i think), he's got range as well.
Would be lovely to take that track you detailed in your previous post pete... i will investigate and log it as a possible.
Thanks for all the comments so far chaps, you okes rock.
Any other suggestions send them this way, doesnt matter how small. even if it has to do with camp tricks and bits and bobs that made your life easier in those PARTICULAR conditions (for nam / Bots).
Ps: Still trying to get Tara Lee Goosen to book my last part of the trip - everything from Nata onwards basically, but seems to be taking forever to correspond with her... frustrating and worrying (even though it will be out of school holidays, i still worry about camp space at these singular remote camp sites).
