Don't get too carried away. I have only seen two broken ones. Enough to make us take the precaution, remember nothing is perfect.

Now I can get my head around the truck axle numbers changing with the trailer hooked on as my ProPride hitch is doing its job and distributing some of the trailer weights to the truck axles. I'm just not sure if it's doing it correctly, as my front axle got lighter (-132 lbs) and the back axle got heavier (+1058)?
Do these weigh differentials sound about right?
Quite normal.

Quote:
So does this tell me I have a hitch weight of 926 lbs? (1058-132)
No, your weight distributing hitch has transferred some of the tongue weight to the TT's axles.
Based on your measured TV GVW weight change, I would estimate the tongue weight was approximately 1110# with approximately 180# being transferred to the TT's axles.
A 1110# TW would have removed about 500# from the TV's front axle and added about 1610# to the rear.
When WD was applied, about 370# was restored to the front axle and about 550# was removed from the rear axle. The difference of 180# was transferred to the TT's axles.
The indicated front axle load restoration (FALR) ratio was 370/500 = 74%. Ford specifies that the WDH should be adjusted to restore about 50%, so, according to Ford, you have achieved more than sufficient load transfer.

Quote:
Yet the trailer is weighing in 71 lbs under the stated base weight. This should not be possible, as the trailer was full of water and had our normal things that we leave in it all the time. (dishes, pots, bedding etc.) So it should have weighed more than the "base weight" not less?
As stated by "cory_can", the indicated trailer weight is 12183-6349 = 6834#.

Quote:
Any input of comments into the above would be GREAT!
Your numbers (so far) look good to me:
GCW=12183 GCWR=13500
GVW=7275 GVWR=7350
TTGVW=6834 TTGVWR=7600
TW=1110 TV TW rating = ????
TW% = 1110/6834 = 16%
frontGAW=3373 frontGAWR=????
rearGAW=3902 rearGAWR=????

The ratings indicated as ???? can be found on stickers on your TV. Many F-150s have a rearGAWR of 3850 or less, unless you have the MAX or HD tow package.
It's also possible the estimated TW of 1110# might exceed the receiver's TW rating.

Truck GCWR: 13,500 - 7170 (actual truck weight) = 6330 weight remaining.

So with actual trailer weight being 6834 that looks like I'm 500 lbs overweight before I add food and cloths into the trailer.
Is this correct?
No. The "actual truck weight" includes 926# of load from the trailer.
The "trailer weight with water" (6834#) also includes the 926# which was carried by the TV.

The correct calculation is 13500-6349 = 7151# remaining for trailer weight.
The numbers indicate unused GCW capacity of 7151-6834 = 317#.

Andrew, was the failed ProPride drawbar discussed in this thread one of the two broken ones you've seen?

Do you reinforce all of the ProPride drawbars you install?

Hi Doug:

Are you talking about the washers that are located here?



and your thinking Andrew is recommending I add (2) washers?

Thanks

Thanks very much for this Ron:

After reading your post I can see that I'm counting the 926 twice. As a result, I'm not 500 lbs over weight - but 317 under weight!

Either way, it's looking like i'm just to close to the top end of the ability of the truck and that worries the hell out of me!

Thanks again

Doug

You can offend me if you want to. I don't mind. Actually, I'm pretty hard to offend.

However, I had a point I wanted to make and almost forgot what it was.

Oh yeah. Blow and suck. I have driven semi trucks, trucks pulling big and small trailers, and motorhomes towing a toad for decades and have always experienced the old blow and suck as big trucks and busses go rumbling by.

If you have a hitch system that totally eliminates that phenomenon, I want one.

Here are the numbers I found to fill in your ??? areas....
I looked high and low and cannot find anything that indicates my TW-rating. your comment about exceeding the TW rating is a concern but I cannot find it anywhere.

Hi Doug

It looks like your angle is pretty well maximized but if you can add a washer or two it will help. When you tighten your torsion bars how far are they from the trailer frame?

There are thousands of people towing much larger heavier trailers than yours with F150's and they have been doing it for years. I have yet to hear of a problem due to overloading in any of them. All the F150's you see towing fifth wheels are well over your weights.

Hi Andrew:

I just ran out to the shop to have a look at the hitch. Cranked the torsion bars up to the point they would normally be when hooked to the truck and it looks like there is about 4.5" between the torsion bar and the bottom of the frame.

While out there I also noted that there is (no) washers at all in the stinger pin. (the one I circles in a photo earlier) Not sure why but there is only the pin. Also noted that the adjuster bars that run from the Torsion cranks to the torsion bars have (three) adjustment holes. My hitch is hooked in the centre hole of the three adjustment holes.

Hope this helps

Thanks

Doug

Usually the TW ratings (with and without WD) are printed on a label attached to the receiver.

Other than the unknown TW rating, your numbers look good to me.
I would not change the WDH adjustment -- that will not change the TW.
If you transfer more load to the TV's front axle, you'll be even farther away from Ford's specification for front axle load restoration.

The present value of FALR = 74% is a good compromise between Ford's current 50% and the value of 100% implied by their previous WDH specification.

Hi Ron:

I just ran out (in pouring rain...lol) and tried to find the label but there is nothing. The truck is not all that old, but I guess it must have fallen off. Even tried to find something on the net but no luck - sorry

Cheers
Doug

Doug, I know nothing about this compared to Andrew and Ron. I did set down and do some math about your situation. Came up with the exact number to use: 2500.

That's the model number of your new truck. While at it, throw a diesel under the hood to help put some weight back on that forward axle. Make it a 4x4. Might as well go all the way.

LOL - Howard I LOVE your math, but my pocketbook might not....
Now if I lived in Texas I could have a BIG TRUCK and actually find a place to park it. More important - have the $$ to pay for it.

Thanks for your most valuable input I will pass your advise on to my accountant (wife) and tell her that Howard says this is the only way the numbers work....
