Like I said in an earlier post I was raised in Twain Harte which is on 108 so spent a lot of time up in the country. One time a pickup pulling a trailer going east to west, was very near the summit......and couldn't make it.........wasn't power.......he was spinning his rear tires.couldn't get enough traction. we were able to latch on to him and get him over the pass. I would not recommend it.....but to each their own. Again, if you've never been over Sonora Pass, do so, it's a beautiful drive........just do it in the correct vehicle
