I was on the CSR early last year, corrugations very bad, destroyed the suspension on many vehicles. If you haven't already, I would suggest suspension upgrade from stock, that's the big killer out there. You may get lucky and find they have recently graded the track. No matter what the case is, you WILL have very bad sections to travel on.
Consider a second aux fuel tank. Also check your insurance and make sure remote recoveries is covered, minimum $10K out there for assistance / tow truck.

Enjoy the CSR, very nice at the right time of year,
