Maputo to Cassacatiza by 2WD

Hi All,

I'm planning to drive from Maputo to the Mozambique/Zambia border in a few weeks. I've got a sturdy 2WD and so need to find a route up there that is do-able without a 4x4.

Can anyone recommend a suitable route? I'm particularly keen to hear whether the road from Tete to Cassacatiza is ok for a 2WD, as this is the only bit on the map that looks llike it might be a bit dodgy!

Any advice greatly appreciated!
