Never fear, CA DMV will *NOT* ask you to parallel park your RV. From the CA DMV Non-Commercial Class A Requirements book:

- Skills Tests. Skills tests are designed to demonstrate your skill in stopping, backing in a straight line, completing a right turn around a cone or marker, and backing into a camping space. These tests are done at low speed and test how well you can maneuver the vehicle.
- Driving Test. The driving test includes entering and exiting a freeway, freeway driving with lane changes, right and left turns into one-way and two-way traffic, railroad crossings, and driving on a grade or steep hill, etc. You may make an appointment by calling 1-800-777-0133. Online appointments are not available for this type of driving test.
The hardest part of the test is (IMHO) the "Pre-trip Inspection Test." The DMV inspector can/will be very picky about what you need to do/have/demonstrate. It basically is what a OTR driver checklist would contain.
I am really interested in this 15 day permit. Can you provide more detail?? I have two friends who are avoiding the test due to no one to help them tow the RV to the DMV. You don't need someone with a Commercial Class A license, only someone with a license adequate to tow. Given the dirth of non-commercial guys, a commercial licensed friend is easier to find.
