We were just there 3 weeks ago. Went up 99, east on the 132, took 49 north, then 120 east. It was really tight turns on the first part of the 120. We were just in my truck, no trailer, and it was still a 30-35 mph run. Everyone started looking green at 37 mph. hahaha.
Any road you take is going to be slow and twisty. Once you're inside yosemite, it's 35 mph limit throughout the park anyway.
The park is very dry. Bridal falls was more like a mist that mostly dried out before it hit the ground. The river through the park is enough to get your ankles wet.
