I'm under the impression that Morocco probably doesn't get tons of rain. That's going to make going without fenders a lot easier. If you're comfortable with carrying all of your stuff in a back pack, and the roads are good enough, then I see no reason not to commute on a road bike.

It's mostly down to personal preference really. I'm a sweat monster and my commute is 9 miles each way, with hills both ways (I have to cross a canyon) so I hate wearing a back pack while riding. I can't even stand a camelback. A lot of people are fine with riding with a backpack. Good for them.
