OC If this is true where do I go to take care of this.

The wonderful DMV of course!!

Depending on the GVWR and type of your trailer (not the actual load but yes the GVWR), you may need to upgrade your license.

Follow this thread to a webpage on the CA DMV website that outlines the classes:

I personally own a 5th Wheel with a GVWR of about 11K pounds (bought it used several months ago - prior to that owned a smaller 6K GVWR travel trailer). I was surprised to learn about the licensing requirements (stumbled onto it by accident), since no one has ever mentioned going to the DMV to take the tests (and I know a lot of people who have large/heavy toy hauler trailers). So I personally needed an endorsement to my Class C license and I took the test several weeks ago at the DMV office in Santa Ana.

What is the GVWR of your trailer and what type is it? (5th wheel or travel trailer)
