Hi Henrick,
Sadly Sally and I won't make it to Expo this year.
However, here are some things I can imagine people would be interested in - many of these are questions I have considered related to travel in Africa:
Places to see / places not worth the effort.
Crossing borders with the vehicle (potential issues with firearms, liquor, might officials expect bribes, how long might customs take, passport problems, limits on money).
Insurance / paperwork (what special legal things must be considered, e.g. carnet-de-passage, permits, proof of title, any mandatory local insurance / road tax requirements).
Advice regarding money changing.
Would a larger truck camper, e.g. DRW, not 4x4 be OK with the roads?
Fears about crime (unfounded?) / avoiding crime / not making yourself a target. experiences of trust-worthiness of locals.
Availability / reliability of vehicle repair facilities and parts availability for US vehicles.
Medical issues - avoiding illness (care about drinking water etc.), tropical disease precautions. Where to get help if needed. Medical insurance?
Each of the above could probably be a whole session on its own, but I suspect people would just like to hear your practical experiences, e.g. "we were worried about XXX beforehand but found we didn't need to bother..."
Making yourself understood - languages.
Customs - do people expect to haggle, do they expect tips, will you get a lot of hassle from people begging or trying to sell you stuff?
Have fun at Expo.
Cheers,
Steve.
