Hi Dave,
Never played with araby yet, but just think a little bit how to command the army. The option you suggest of adding camels (cav) is interesting by the choice of move a brigade of two camels raiders without distance penalities, but quite risky. They have -1 command so should be the general who take the chance. As I see araby army has very few command characters (Ld, 9, 8, and 7) which I guess is difficult to manage moving a 6 or 7 brigades, so I believe trusting in camels could make you fail general orders and stack the army.
Guards brigaded improve the first order with general to command to 10. So I think is more valuable having a 3 unit brigade of guards to move for sure 1 per turn without distance penalities.
Even also considered to get rid of the camels and maximize guards, but I like the idea of having camels in the army because takes a lot flavour and I like the concept, so finally I decide to introduce it in the list.
Are my thoughts rights or should I max camels and get rid of 1 guard?
