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.

The 'need glasses' comment back at 'cha.... 🙂

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.

The 3-axle trailer had pintle hitch, so WD was not possible even if I wanted it.

Actually, it is possible, works fine. Just not very common for sure.

And for added grins...

Here is 2016 F350 SRW, so looks like the axle towards the rear bumper is dually thing.

Again, the specs are the specs that I posted with no difference for DRW. I guess you could always take a trip to a local dealership and measure. 😉

Take a look at the overhang in this table. NOTE: it's the same for both SWB and LWB at 52.4". Obviously, if the overhang is the same for both SWB and LWB, the extra distance is at the front of the bed for the LWB.

To see what this looks like you can look at the Build a truck option as well. Click on 6 3/4 and then on 8 ft and you'll see the image to the right change.

The ad may say it, but they aren't.

Both pictures are about the same scale.

Again, I am not sure when and what models, but compare rear overhang on those two F350.
The white one is 2013 but SRW.

Short bed and long bed... Apples to spaceships.

I believe the dimension has been 52.4" for years... Regardless of whether it's a short box or not.

If you take a look at new Superduty, the rear axle is at about 70% of the bed, when on older SD it was at 50%.

What years are you comparing? I don't remember the axle being dead middle of an 8 ft bed.

Correct. However you are not going to see a fundamental change in how vehicles are designed any time soon.

It already happen.

Not sure what year the difference happen, but till early 2000' it took F550 to have rear axle at the rear.
That makes for longer wheelbase, but with coil springs, front wheels turn more, so the trucks are manageable at liquor story 😉
My 172" base 2007 SD makes about the same turning radius, what my 2000 14x' F250 (short bed supercab) did.

Observe how tow trucks are build. Their rear tires almost are touching the bumper and they tow without WD having tons on the hook.

Correct. However you are not going to see a fundamental change in how vehicles are designed any time soon.

Plus what's good for towing is not good for hauling. With the axle at the extreme rear of the vehicle, any weight you put in the bed is going to end up 1/3 to 1/2 on the front axle of the truck. It won't take much to overload the front axle. Not to mention the abysmal turning radius, undesirable for what is normally a daily driver.

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

You'll have to ask the people doing the rating.
