Length of RV allowed at La Verne?

Does anyon eknow the length of RV allowed at the La Verne camp site for the Folks Fest? Thanks!

18’ is the stated limit by PB if you’re looking to use a vehicle pass. 35’ plus in the RV spots with an RV pass. You may be able to get away with 19-20 feet in the vehicle spots, but because there car parking spots, anything longer will actually be a problem with cars passing.

Thank you!
