RHD or LHD has proven to be irrelevant from a driving perspective - well, unless you spend a lot of time in drive throughs. I drive a RHD nearly every day. Our J8 is RHD, the LJ78 is RHD, as are the VDJ78s. However, there are a few countries that do not permit entry of RHD, none of which are on our route. We do field the question of "why the VDJ78?" The easy answer is the motor - I cannot overstate what a pleasure it is to drive.
We are covering a nice chunk of Africa - the stuff we want to see.
The current plan is to drive the trucks back up the Panamerican in South America after completing the route to Ushuaia.
