Think this was just a stunt??  Just to get a pic?

NOBODY can be THAT dumb can they?

sure they can...

google 'burlington skyway bridge accident' , find the one where the dump trailer  hit the bridge with the trailer UP !!!

It's illegal for non-commercial drivers to tow more than one trailer here in Ontario.

That 'rig' would count as THREE trailers if the 5th wheel dolly is a 'trailer'...

 I've seen pickups pulling camper, pulling a large boat on I-29 between Omaha, Ne and Sioux City heading for the Iowa lakes or the reservoirs on Missouri River in S. D.  

 And in July & August you see the pickups pulling camper and a trailer loaded with motorcycles on behind on I-29.  Expensive outfits; figuring an over $100,000 pickup, over $100,000 camper, $15,000 trailer and 4 x $40,000 bikes. Over $350,000 in vacation toys.

Unfortunately So many people will now take that as a challenge.

I know of someone here locally that was going to Florida to ride his motorcycle. Instead of riding the motorcycle and having a nice trip, he hitched his 4 door pickup pulling his 20' enclosed trailer behind his tour-bus sized motorhome. total length was nearly 100' and because it was a RV he wasn't required to go into any scale houses or DOT safety checks. Only the motorhome had working brakes in this setup.  ANYONE driving an RV should be required to have an endorsement on their license for the size of the RV. Also anyone pulling a trailer should also need a trailer endorsement.

  Maybe this is what we get for trying to make cars idiot proof with all the thigs cars have nowadays instead of just being a car. 

skechy report but in Texas, someone decide to pass a 'superload' (160 TON pipe) on the shoulder. he lost.

BTW up here, anyone with basic license can drive a 'school bus',modeified for just 4 seats and no sign on it !!!

That's actually a legal load.  Driver will need a Class A CDL, and in most states, an endorsement for doubles and triples.

Let's break it down:

First off, the Gross Combined Weight of the tow vehicle (tractor) must not be exceeded, and Gross Axle Weight Ratings must also be respected. That appears to be an F450... but COULD be an F550.  My F450's were typically 18,000gvw, with 6000lb steer and 13,000lb drive.  Without the (heavy) service body, my chassis wet weight was 8300lbs.  With the 9'x12' service body EMPTY, that went to 10700, and with all my tools and equipment, it was 15,200.  THIS Truck's GVW is certainly not exceeded with that factory pickup box (they're only about 900lbs) boat on top, that fish'n ski only weighs about 2100lbs dry (tandem axles are for durability when running with water in the baitwells).

The dolly accepts a significant amount of the 5th wheel's nose weight.  The camper has tandem singles, they're clearly nothing exotic... the 'standard' largest axle capacity common to campers is 8 on 6-1/2" bolt pattern 7,000lb, and trailer tires commonly match this.  Two 7000lb axles, plus 10% on the nose comes to 7+7+1.4=15,400lb GVW for the trailer... and probably under 1000lbs for the dolly assembly... so 16400 if it's fully loaded.

The enclosed trailer at the back appears to have 5-bolt axles, which  puts them in around the 3500lb class... so that trailer will be in the 3500+3500+10% = 8000lb GVW range.

So let's say the Tractor's GVW (not it's loaded weight) is 16,000, TOWED stock comes to 16,400 + 8000, for Gross Combined Weight of only 24416.

The pickup's Gross Combined rating ('towing capacity') is upwards of 28-30,000lbs.

As long as all axles have brakes (in this case, electric), all lights work properly, the total length, height, and width combination is within the driver's CDL endorsement, this is legal, and there's towing capacity to spare.

A bit extreme for some?  perhaps.  Dangerous?  Certainly not when done properly, by experienced professionals.

Would I do it?  No... but that doesn't make it idiotic, and I would know-  I'm a well-experienced  and versatile idiot.

   This is why I've retired from daily commercial driving and limit my highway travels otherwise. No one seems to have any common sense or courtesy any more. 

There's insufficient clarity of the photos posted to determine the lug nut count or tire size, but I know my F450 service trucks well... my team's fleet consisted of 8 F450's starting with 2003, all the way up to 2019... and yes, one COULD get an F450 with a pickup body, as we changed out our entire fleet every two years, or after ONE of the trucks hit 100,000mi.  After we removed our service bodies, our F450's were fitted with dually pickup bodies and sold to construction contractors and RV'ers.

From these photos, it's clear it's a Crew Cab, and a DRW.  Let's assume it IS an F350, and while I don't know the year, most of the specs don't change much year-to-year (except the introduction of the aluminum body, which reduced tare, thus yielding a higher capacity at same GVWR).  As an example, I looked up the 2019 specs sheet, which lists the F350 Crew Cab as a 14,000gvwr truck, and advertises it's payload capacity as 6550 (for the 4wd) and 6970lbs (Rwd)... the difference clearly being that the 4wd version had an extra 450lbs or so of driveline to lug around.  That boat weighs under 2100lbs, so there's a whole lot of load room left.

Towing capacity is expressed in Gross Combined Weight, and nothing else.  It doesn't matter if the entirety of the load is in draft, or distributed to the vehicle, it is part of the full combination.  In a 5th wheel application, a significant portion of the load is borne upon the tow vehicle, just like a semi-tractor, and when that hitch is placed slightly forward of the rear axle, the towed load is proportioned onto the front, as well as rear axle.  When a bumper hitch is used, the tongue load bears well BEHIND the drive axle, and the result is a higher axle load than the actual tongue load (because it is now an overhanging load) and also, the steer axle is reduced... lifted up.

In the case of this setup, the 5th wheel dolly acts just like a heavy-haul 'booster', carrying a significant amount of tongue load, but keeping a little on the hitch to assure stable tracking.

Gross Combined Weight Rating for the F350 goes all the way up to 31,300lbs.  There's no reason to suspect this rig exceeds the truck's GCWR.

It is a legal configuration in many states, and I've weighed plenty of them.

They sure do make F450 pick up trucks. Bought one brand new in 2010 and theres a 2017 sitting in my driveway right now. The truck in the picture has 19.5's on it as well.

re: just wanna know how high the bow of the boat is.

Hopefully less than 13'6" if in Ontario !!!!

That's a valid concern-  based on the angles of those two photos, it looks to be mebbie a couple inches higher than the top of the RV.  If there's an AC unit, open vent, or TV antenna atop the RV, then they're about the same height.

I see that all the time on the Parkway.

That is more than likely a professional delivery guy for a big camper and boat sales company.

It is definitely not just some consumer individual trying to get attention.

I see them quite often with a boat/trailer loaded thus and three trailers in tow, either camper trailers or boat trailers or a mix.

I have been asked several times to bring my F350 and join them, but I had much rather do my long-hauling in a big truck, W900 or 379.

That is not to say that, if funds were low and things were tight, I wouldn't hook up and go.

Likewise with my Class A; there is no differentiation between doubles and triples; if you qualify for one, you qualify for both; I believe the endorsement is either "N" or "T" ; I have both N and T; I think the "N" is "Numerous" meaning doubles/triples and the "T" means Tanker.
