Another view to consider. You would probably enjoy the trip better if you do not bother with 49 south of Auburn to Plymouth or so. Following 49 through Placerville was real tight and took up more than one lane for a couple of turns in the city. 49 is a great scenic “Racer Road” for sporty cars and fast bikes but at 54’ with a toad the 60 mile drive north from Jackson to I-80 took 2 ½ hours and was more work than it was worth last Sept. The road meets the legal width requirements for a 2 lane state hwy but where there are 15mph curves and no shoulder beyond the white line or a rock wall at the white line to the right, Hwy 49 drives very narrow. Also, turn offs are not very large or long and it is hard to clear the lane to let traffic past. Do you have the right to travel the road? Yes, but it may not be right considering the speeds you would be driving to feel safe. I prefer to be a good neighbor RV’er on the road and not some “Blankity blank” moving road block. It’s a very pretty area with lots of little shops and friendly people. Be safe.
