If the road is dry, a high clearance vehicle and some basic off-road skills is all that is needed. The narrow 3 mile trail consists of a number of large berms that divert water off of the road. My stock Jeep Cherokee didn‘t have any problems and never grounded out. The real challenge of the road is it‘s narrowness. The first mile of the road heading up from the trailhead is fairly wide and has plenty of spots to pass or turn around. About the 1.0 mile mark is a switchback with a large pullout (relatively speaking). Past this point, the next 1.5 miles provide almost nowhere for two vehicles to pass. Forget about turning around during this section. At roughly the 2.5 mile mark is another switchback with a wide pullout for passing / turning around. A half mile remains to the radio towers. At the radio towers are a handful of camping spots and if you‘re creative, quite a few parking spots. The road above the radio towers is very smooth but offers only a handful of parking spaces.
I recommend heading up the trail early in the morning to avoid any head on traffic. Keep an eye on your odometer so you know exactly how far the last pullout is just in case you need to back up or try to convince another vehicle to go back. Good Luck!
