He needs to invest in a bigger, safe trailer. I put three tractors (occasionally four) on my gooseneck with no problems and DOT doesn't bat an eye.

Just checked, LEGAL in Ontario ( pickup, <75', <4600Kgs ,black plates) !

Looks like rear trailer has hydraulic(inertia ?) brakes, assume front has electric.

Provided it's loaded right, no different than a 'B-train'.....

When first seen picture, was thinking that I never seen one like that before 

Only legal for in Ontario for registered commercial vehicles (and if the driver has a CVOR). And the MTO officers are always a little confused as to whether a pickup with a GVWR of over 20k is 'commercial' or not. They're sometimes happy to ticket you for driving an F250 past a weigh station without pulling in, even if it's registered for personal use only and has no load or trailer. But other times you'll be pulling a float with the same F250 and you'll pull into a weight station to do your due diligence, and they'll get angry and ask what the heck you're doing pulling in. Driving in Ontario has so many trivial laws, loopholes, regulations, and counter-regulations that even the MTO can't keep them straight. One page on the MTO website lists double trailers as legal and mentions nothing about commercial permits being required. Another link to the highway traffic act lists it as legal for motorhomes (which are NOT registered as commercial vehicles in Ontario). And yet another link on the MTO website says it's illegal to tow any double trailer setup unless it's a commercial vehicle. A trifle irksome for the common man to figure out.

Dan, that is just CRAZY!!

Dr....NICE!!  I imagine it is just like backing a hay wagon??

Don't think we'd get away with something like that over here in the people's republic of England, otherwise I'd be tempted just to see if my old 1.9D Citroen would pull two at once!

You sure it's legal?  I thought to pull doubles the first one had to be a 5th wheel/gooseneck?

There's two visually imposing things that get peoples' hackles up necessarily:

First is that there's two trailers.  Not a complicated or difficult deal.  Backing up can be a challenge, but the key to ANY trailer backing, is having the proper proportions of distance between the tow vehicle's hitch to centerline, and the first trailer's hitch to center of axles.  If the tow axle distance is extremely short (or directly on) the tow vehicle's centerline, the tow vehicle's angle can be changed significantly with no impact on trailer vector, but if there's a long distance between, the swing of the tow vehicle's hitch WILL cause significant change in trailer vector.  Having an extremely short trailer 'toungue' length will make it nearly impossible to back up without significant adjustment.

once that first trailer backs well, then the same applies to the second trailer-to-first trailer relationship.  To back it, all you do, is focus on where the REAR trailer's hitch ball is going, and steer the FRONT to direct the rear... it's not that difficult if that front trailer's proportions are correct.

The second visually-imposing circumstance, is that they're TRACTORS... they're tall, and wide, and look ghastly heavy... but they're not.  When there's no ballast in the tires, no extra iron, they're actually pretty light.  I went to shuffle my WD up to the front shop last night with my little Kubota BX1800, it picked the nose of my WD right up and pushed it like a wheelbarrow.

As Doc's numbers show, it really isn't a heavy load.  Those two trailers, overlapped (nose to nose) on a tandem axle trailer would be no different in most any other circumstance, just a heavier trailer to carry both at once, and probably not as easily balanced.

His front trailer is the special one... a single axle, looks to be 8 bolt, that's usually 7000lb capacity.  10% rule means the hitch would be carrying 700lbs, which for the F150, is entirely reasonable... it's a Class 4 2" receiver, good for 1200lb tongue weight and 12,000 towed capacity.  He's at 12,300 gross towed... but 700 of that is on his hitch ball, not the trailing axles.  

The front tractor  is 5400+1700 for 7100lbs, but again, 700 on the tongue means 6400lbs on the 7500lb axle.

Now add the rear trailer, that's 1600+3600 for 5200lbs, but 520 of THAT is on the tongue to the FIRST trailed, so add 520 th the 6400lbs there, and that makes the front towed unit 6920.

The loading here is impeccable.  It'll tow wonderfully, and having brakes on every axle means it's slow just fine.  The F150 will have to work to climb and bring it up to speed, but will have no problem keeping it under control.  ;-)
