I've driven it several times. Spectacular scenery and if you're into photography you'll no doubt be blocking traffic because you just can't resist stopping to take photos. The switchbacks are narrow so if two camper rigs should meet someone will have to move to a turnout. Not the road to be towing anything behind your truck/camper, though!
As someone above said, at times the washboards can be severe - much more of a problem to a camper than the switchbacks. Make sure everything in the camper is secure. I once had a water line crack due to the severe vibration.
