The level of detail on the Wanderlust maps .. or Garmin world map ... well it gives you teh main major roads .. not the single tracks .. unless those have been contributed by someone .. and those should be well enough identified .. So i don't hink that will be teh problem .. more likely the inaccuracy and lack of deatil will.
I'd recoment Tracks 4 Africa .. they have the southern bits well covered .. lacking in teh north ..
Island Oafs MorrocoTopo is an exclent map .. for Morocco.
and you'll find some good maps on cgpsmapper toos - Dacar, Gabon IIRC, umm and one other .. you'll need to generate the preview files for those though .. bit of work .. but can be done ..
