Weight distribution hitch questions

crossent

Just purchased a carson 14' toy hauler for hauling the bikes plus extra space for the kids. Trailer weighs 3200lb with 450lb tongue weight dry. I have the Reese titan on both trucks and run the reese 48" extension. One shop tells me not possible to tow with my current setup because I would need to add the tongue weight of trailer plus the added weight of the camper past the rear wheels and that would be what size distribution bars needed and since the Reese extension is rated for 600lb tongue and 6000lb pull I cannot go over 600lb distribution bars and therefore would be useless and have no effect. Any help would be appreciated.

I have/had, 250's, 350's, 450's, 550's.. The axle to rear is the same regardless of single, duals, short, long, naked, dressed, polka dots or political affiliation.

You make broad statement on your limited experience.
You are right that Ford lists all rear overhangs at 52", what leaves about 50" for cab to axle, but F550 are also coming with about 80" cab to axle.
The white truck seem to have the 50/50 box, but I keep measuring the front of the box to rear overhang of new DUALLY trucks and no matter what picture I take, it is coming like 64/36.
Would probably take a visit to a dealer with tape measure to check it, but put your tape measure on this picture.


Update. Went to Ford dealer to see dually I like and took tape measure with me.
This is what I measure.
The rear overhang from axle to end of the bumper is in fact 52" but the bumper alone is 9" and tailgate thickness about 5".
So on the picture above the bumper is barely visible, while comparing to bed floor the axle is placed like 60/38".
With hitch sticking behind bumper the proportion might not make big difference, but that design gives me much better weigh distribution with camper -comparing to older trucks.
Took quick look at shortbed, and the axle is at about 45% of bed floor.

This has my vote for being the funniest thread Ive read in a while-some actually relating to OPs question.

Kayteg1, I don't know how excited a dealer might be with a tape on new truck but if you draw a line on any of the pictures you uploaded, on the bed -centered at wheel well opening, easy to see the distance to rear of truck is the same. Both the SRW & DRW long bed trucks and the first picture of the short bed 'platinum'. Granted on the picture of the grey DRW the picture is skewed, the extra depth of outer wheel from the prospective taken, makes it 'appear' closer to rear bumper, but its not.
I'd be really amazed if you 'measure' what you seem to seeing in the pictures as being true and would like to hear- however the pictures you uploaded to back up what your saying actually verify the opposite?

Attitude explosions are normal thing on net forums, that is why I never volunteer for moderator job.
It is very hard and unappreciated no matter what.
But look at positive side.
I learned that combination hitches with more than 12k lb do exist.
Reality Check learn that his setup leaves much to safety desire.
Others will gain from it as well.
Beside I just notice on the picture above that Dodge dually has rear axle not far from 50% of truck bed as well.

A bit of a highjack from WDH to safety chains. 😉

YES...Here in IOWA all the time.
If you are toting a flat bed or cargo trailer behind a pick up be it a dually or not, you are considered commercial and subject to the regs thereof and you better have your act together and have a CDL
One sees the vehicle enforcement guys pulled on the side all the time around here with them.

Sure hope I don't meet that rg on the road with that wimpy safety chain set up

Why a WD hitch? well without it my 48" supertruss extension is rated at a 600# pound tongue weight and with WD bars its rated at 1200# and with my horse trailer I need every last one of those 1200 pounds to handle the tongue weight and it has done so safely for 6 years of use.

The dead weight of the tongue pries down on the shank/extension. The WD bars pry up.


I think we just have a terminology problem. My point is the weight doesn't disappear or is attached differently just because you hookup a WDH. The WDW is designed to push up not down on the hitch, but to do that the force still goes through the hitch. There are no other attachment points to the truck. If you are worried about hitch strength, a WDH isn't going to fix it. The lever arm is still 4 feet.


Then why are the hitch and the extension both rated for more weight WITH a WDH ?

No , the weight doesn't disappear , It is distributed differently through the attachment point . The upward force is subtracted from the downward force to lessen the downward reaction at that point . Then it is transferred through the frames to the front axle of the tow vehicle and the trailer axles .


Here are some weights with an extension and a WDH. Note the weight change as the WDH is tightened (links #).



Most importantly, A WDH greatly reduces the dynamic loading on the receiver because as it flexes, the bar loading increases proportionaly.

The combination hitches come with 8000lb ratings, going to 12,000lb with 2 5/16 balls.
The one on the picture sure doesn't look like 2 5/16"
Just becouse someone did monkey job, doesn't make it doable, or usable in common sense.


Insufferable...







Yep... But then, what do I know. You've already told me I have 'limited knowledge'.

^^^^ Seriously, when is the last time a grey shirt "DOT'd" an RV? Do you even know anything about what you're asking? Can you tell me the difference between a Level 1, 2 or 3 inspection? Did you read anything further or just look at a picture? Tell me this: what size chains does one actually need on a 3000# trailer (garden tractor trailer) to be legal.

Once again, you point out the obvious. But you did get part of it right at least.

You stated it can't be done. I was just helping you out and increasing your knowledge a bit. Take it as you did, I'm not surprised.

That hitch is actually very smooth. It's not an air compressor, etc (balanced load with net zero tongue weight), so it doesn't 'slap' up and down. But those that tow a lot of heavy equipment, etc, would know that. It's as smooth as any ball job. Just easier and more secure.

I have pintle hitches to 45 ton. Big deal. You towed 18k. Big deal. But hey, great way in changing the subject that WDH isn't possible with a pintle.

You are partially correct though, as this particular hitch is light weight. It's only 16k. But it pulls a max 10k trailer. How you randomly came up with 8k is amazing I'm sure. Maybe you meant 8t. Yea, that must be it.

The chains, which were factory, were in fact not 4000. I believe they were 5200 (WWL x4 of lowest grade). They could have been stronger than that, but as I'm sure you know, they don't often mark chains smaller than 5/16". They are now 3/8" x 43's. Does that make you feel better? I fully agree that most trailers have to small of chains, but they base it on 'breaking', not WWL, which goes to what the definition of "ultimate" (USDOT) refers to. But then, you knew all that.

Thanks for the compliment I guess. It this is a monkey job, so be it.

I can't wait to see what wisdom you bestow upon those of us who have limited knowledge, next...

As has been pointed out to you (well done jimh425), the discussion turned to the 'rear overhang' issue (which you brought up). Feel free to take a tape measure anywhere you want...to verify what is common knowledge.

It appears that there is confusion at your end now about what the discussion was about...cab to axle or rear overhang. You showed pictures of short boxes and long boxes and duals...and then had the obvious pointed out to you. But there is still confusion????

I'm sure others can sympathize with my affliction over your writings. Seemingly all knowing on all subjects. It's wearing. But, according to you, I have limited experience, so what do I know.

Carry on...
