OK, so an inauspicious start. It's our garden in Edinburgh and not the African plains or a desert oasis. But that's the tent we plan to use for sleeping in on our ascent of Kilimajaro, and tonight we are going to try it out. We reckon it should be cold enough for us to get some idea of how good our sleeping bags and thermal mats are. Once in Africa we plan to use the Hilux's roof tent for most of our camping, but this lightweight little fellow (2.9kg) is coming up the mountain with us.
