Liberia is a bit problematic with a RHD vehicle. At the Bo-Waterside border crossing from Sierra Leone there is a large note stating "No RHD vehicles are allowed to enter at Bo-Waterside!".

A British couple who went through there a few weeks before us got some trouble from the officials but were eventually issued with an official exception to transit the country. This piece of paper was for free but limited to 7 days instead of the 1 month validity of the visa.

Just to make things more confusing we went through without problems and even showed the big boss of the border crossing around our car to explain rooftop tent, water supplies and so on without him even mentioning our steering wheel. :D

though others have past through. and seemingly entered Bolivia and Chile. Sometimes various officials may use the confusion in an attempt to get bribes.
