It is odd as that link you posted does list California as one of the states that it is legal.
However, we were having an around-the-camp fire discussion on this once and this is the distinction as I understand it: A motorhome (or what California calls a "house car") can NOT tow two trailers but a pickup truck can.
Passenger cars are not allowed to tow two trailers and a "house car" is actually considered a passenger car by law. A pickup truck is considered a "motortruck" by law and CAN tow two trailers.
Of course, the length restriction of 75' applies but the big "AND" is that a Class A license is required of a California resident to tow two trailers. An out of state resident can tow two trailers if they are legal to do so and meet their base state requirements but must have a valid DOT medical card/certificate.
So, the what we surmised is that a California resident with a pickup or a "motortruck" can tow, say, a fifth-wheel trailer with another trailer attached if it's under 75' or they could double tow any combination of a boat trailer, small cargo trailer, TT, etc. as long as the combination does not exceed 75' ...AND, they have a Class A license. Towing a trailer (single trailer) heavier than 10,000 GVWR also needs a Class A license. And the way we understand it, in California, the only Class A license is a CDL (is that correct?, California residents please confirm).
However, a motorhome (or "house car") can't
double tow at all (according to VEHICLE CODE SECTION 21700-21721).
It's explained here and appropriate links to the applicable Vehicle Code Sections are given: click here
Do I have all that correct?
