I only wish I could post the photo's that I have of me and my utes doing this regularly, sometimes with 3 trailers in the outback of SA.
I have two 7x4' tandem trailers, both fitted with receiver hitch towbars and trailer lights socket on the rear of them. Normally these trailers just tow each other. I can with two vehicles, use each as a lead trailer and each tow a trailer, for a total of four trailers, or use each of the leads together with another trailer as a triple combination.
I did have several photo's on www.uteman.com.au, but the site appears down for maintenance at the moment. However the author of www.uteman.com.au did an article of me and my exploits towing two or three trailers behind my ute. The book is called Beut Utes #4.
Normally, I only regularly tow two trailers at highway speeds on the highway, and will rebuke the comment that multi combination trailers sway and are dangerous. At 110km/h, the rear trailer is remarkably straight, to the point you can quite easily forget that it is there. Even the one off time towing three at once (all empty) on the highway at 110km/h also proved to be quite stable. Deliberate flicks of the steering wheel resulted in a small movement of all trailers at less width than the total movement of the ute towing them. Even when deliberately trying to whip them, as soon as the ute is pointing right ahead with the wheels straight, so the trailers fall straight into line as well.
Whipping trailers is a bit of a myth these days. Whipping trailers is not caused by errant steering, but by looseness in couplings which amplify and lateral movement, pintle hook couplings are notorious for this. However with good fitting standard 50mm ball couplings, any sideways movement of the towing vehicle cannot be amplyfied, therefore the whole combination is only a repeat of what the towing vehicle is doing, if the towing vehicle is towing right ahead, then the trailers cannot do anything else other than follow in a straight line.
I also know I am not the only one where I live that uses a standard box trailer as a lead trailer, although the last I looked, neither of the other two guys had a trailer lights socket fitted for the towbars on each of the rears of their trailers.
I will still try and see if I can get my photo's up. And unlike the clever imagery (doctered) by Neesan and the work shirt company, my photo's will show the real deal.
Cheers,
Dion.
