sand/dust is the no1 enemy in the desert... a very very good air filter... preferably a snorkel to get clean air. Filter should filter the tiniest dusty particles but let the air flow!
keep spares... like hoses, filters, lubbricants, a decent tool kit, a fit aid box, an air pump etc
and remember if this is the first time ur rallying.. dont race to win.. race to learn
