I have a 30' Bounder and got it into a 24' max site in Ventura. I pulled into the site, and the neighbor was watching. I got out, looked at the wheelbase, it looked like it would fit, so I turned it around.
The jacks just hit the parking bumper, so I put down 2X10 that are 12" long, and that lifted the rear enough to clear the jacks over the parking bumper. Backed up until the tires touch the bumper, and it fit! The rear jacks where just on the pavement.
Neighbor was walking her dog, and commented to us "I don't know how you folded that in half, and got it to fit! I thought it would never fit when you pulled in forwards! "
With time, you will get used to parking the RV in many places.
Good luck!
PS: How in the world do you get reservations in Yosemite Valley? I hear they are almost impossible to come by!
