Ok Gord, I have been through this a bunch of times and asked many commercial highway patrolmen. Only in CA though. As long as you have a commercial class A with doubles/triples endorsement you can tow up to any length. I was told you can be 100' and be fine. If you have a restricted class A you can only be 75' overall length. Also here's the kicker,,,, NEITHER of the TWO trailers in TOW can be more than 28'. Now here is where it gets tricky. does it mean over all length of the trailer or is from kingpen to rear axle or is it from front axle to rear of trailer????I was told it is more or less for you to interpretate what the states in the DMV handbook and hope you don't get into an accident and or get a asshole patrolman that wants to mess with you. This all from CHP in CA. I used to tow with my 28' fithwheel trailer and my cruiser with my crewcab. It was 88' all together. Fun stuff and everybody looks at you doing it lol
