The most "technical" parts are ruts from the rain. Sometimes they go straight down the middle of the road, other times they cross at different angles. It's nothing hairy, just go slow and pick your line. Air down and bring something (CO2 or compressor) to fill your tires at the end. Keep your tires on the high points, and cross the ditches at an angle, one wheel at a time. There are steep ascents/descents. You should be in Lo range, it's a good idea to put it in 4wd. Better to be in it when needed, than get hung up and have to engage it. Get into lower gears in the transmission. Don't be afraid to drop into 1 or 2, just make sure your rpms aren't too high first. Remember, uphill upshift, downhill downshift. Crepuscular rays (shafts of light in the dust) on the windshield make it difficult to impossible to see the trail ahead sometimes. Go slow, drive through it and let your eyes adjust.
It's rare, but expect to see a little traffic. The person traveling uphill has the right of way. The theory is that they may not be able to get going again if they stop. Always stop for bicycles. We had a group of 4 heading the opposite way. The leader waved me through. Be courteous and drive slowly so as to not kick up much dust since they don't have windows. When you're passing someone (bike or car), you should let them know how many rigs are in your group. If there's a gap or straggler in your group, there's a better chance the other person will wait (that's the hope at least!).
