Kurzzeitkennzeichen OK to pass Morocco?
 

A question for experienced German travellers I guess...: I have a German-registered car that I want to drive to Gambia. It's a bit of a hassle to get export license plates, but very easy to get a 5-day valid 'Kurzzeitkennzeichen'. No technical inspection is required for the last. I believe that officially you can't even use these out of Germany? What if I would do use them, and show up at the Morroccon border? Would they recognize this kind of licence? Are they unforgivingly tough on paperwork, or happy to be bribed? What about the Mauretanians lateron?
Thanks for your reply!
