@Islam Soliman Hi,
I have just signed up for the drive:
Mitsubishi Pajero 5-door, yes to low and high 4WD gears, tow hooks etc.
I go dune driving about once or twice a month but I have never been part of a convoy so consider me a newbie (though not completely new to sand driving).
I have a two way radio, tire inflator, tow ropes but no flag.
Looking forward to the drive.
Jan
