I drove this route north back in November, returning my son's F350 back to his house. Had taken his trailer down to factory in La Grande for warranty repairs. His truck is a crew cab long box. First time for me on this road, and it wore me out!!! I don't get motion sickness, but even going 25-30 mph and much slower on the corners, I was getting dizzy, and light headed at times!!!
Our trailer and Excursion are 53+ ft overall. I would have to travel this road a whole lot to want to take it that way!! I'm sure that I would be taking both lanes on the tight 180's!! And, I'd have to make sure the wife's gag is tight so I could concentrate on the road!!!
That said, the road is in great shape, well maintained, and can be done by just aboot anyone or any veh combo if you desire. Unless I have to go that way, I'll look for another way to my destination!! Just know that (for the driver) it is a DRIVE not SIGHTSEE road!
