License class requirement in California

For those in Ca. who are towing a 5er, and may be interested, we have learned first hand from DMV what is required-because we just purchased our first 5er that is heavier than 10,000 but less than 15,000. The drivers manual was confusing because it initially states that with a Class C you are allowed to tow a fifth wheel that is more than 10,000 but no more than 15,000. That sounds pretty straight forward but,like most things in CA, it's never that easy. If you read down a few pages in manual there is this stipulation: you may tow with a Class C license but you also must have a "Recreational Trailer Endorsement." To get this "endorsement" the person towing the vehicle must take two tests. The first is the standard test that is required of anyone who is getting a class C license. The only time this isn't required is if the person towing the vehicle took the class C test within the last year. The second test that is required is the Recreational Vehicle and Non commercial Class A Trailer Law Test. A vision test is also required. There is no requirement for driving test and no medical requirement. Like another poster shared: to not have this endorsement could cause real problems with insurance if driver and vehicle were ever in accident.
