I don't think I can add much to the suggetions already given, but as I did a lot of desert driving in Egypt and Jordan in the '80's and '90's let me add my two cents worth:
a) I second the advice about finding another vehicle and travelling in convoy. Not necessarily the same vehicle for the whole route, but I don't advise doing any of the off road north African ( Egypt/Sudan) parts on your own.). When I was much younger I did so on an overland trip across the eastern Sahara from near the Libyan border to the Nile, and I wouldn't do it on my own again.
b) nobody mentioned a compass, but I would think about a good dash -mounted one to supplement the off road nav feature, plus of course a pocket one.
c) winch and tow ropes
d) blanket to cover your windshield in a sandstorm
e) a sense of humour
Have fun. Wish I could come with you, but family circumstances don't allow.
