was gonna throw this in there, lawyers would be asking for policy limits and maybe more if found at fault in an accident like this, definitely more to think about when your business is involved

 

OP's truck is an HDPP with 4800 lb RAWR. His rear axle probably has 2300+ lbs of capacity available just based on knowing my 2014 supercrew 6.5' bed Lariat has a 2700 lb unloaded axle weight.

 

The leverage does increase the rear axle load by more than just the hitch weight. The weight that is unloaded from the front tires due to the tongue weight is also put on the rear axle. Its a ratio of the distance from the hitch ball to the rear axle vs the rear axle to the front axle.

Which is also why I think its bologna that the 500 lb rating is the same for all F150's regardless of wheelbase or frame, but its just easier that way I imagine.

 

You are correct. The less easy way requires they run all chassis configurations through the J2807 test. That would be 6 trucks to test for just the F150, and all the other trucks, SUV's and cars and their configurations.

 

You, sir, do not comprehend this.

 

Oh I do because I own a construction company and have owned more work trucks and vans than I can count. We probably move over a million $ in material a year on our punchlist runs completing projects.

Unless you are overloaded the front axle should remain relatively the same.

And yes I have scaled several times and none have been over with some specific loads we haul. I have also never installed overload springing systems on any dedicated work truck.

I would encourage you to read the owners manual, guides, and go off the engineered ratings. Run WD or change to a better designed hitch to keep from overloading.

The stock hitch set up on the F150 is garbage.

 

No aftermarket hitch changes the understeer and handling requirements used in the J2807 testing that determined the WC and WD ratings of the trucks. You can put as much hitch as you want back there, the TRUCK is still rated for only 500lb weight carrying.

You are telling everyone to RTFM. Care to point out in the manual where it says these trucks are rated to carry more than 500lb on an aftermarket hitch?

 

Can repost some old screen shots.

FACTORY hitch options. Note: EACH hitch has weight carry capacity labeled on it, the capacity in the chart below is ONLY for the factory optional hitches.

Do not exceed GAWR or GVWR with tongue weight.

Maximum weight requires WD, the chart is shown above; which is 9,100 on my current delivery truck.

 

More references to THIS FACTORY HITCH.

Below is where after market hitches hang the weight. Over the rear axle. This is why engineers label these hitches differently than the factory junk.

 

I'm still waiting for you to respond with what I requested. Nothing you posted says we can have more weight carrying capacity with an aftermarket hitch.

Also, your thoughts on "hanging" weight with a hitch is misguided. Aftermarket hitches don't magically place the weight somewhere else. They aren't physics defying structures, nothing is.

Aftermarket hitch designers design hitches the way they do because that's the way they've always had to do it. There's no designing the hitch how they want it then fitting the vehicle to the hitch, they have to go with what they are given. They don't extend a bracket here or there because it's better, they do it because there was an attachment point at that location and the distance between the bolts is far enough that the weight placed on the ball won't shift the hitch against the vehicle's frame and cause the bolts to ream out the frame, or the frame to shear the bolts. Two problems not eliminated by the oem hitch design.

The name of the game for aftermarket hitch makers is profit. You make more profit where you spend less money. That's why some of their hitches have hardly any metal at all.

Here's a Class V, rated 2000lb WC, doesn't appear to extend far into the frame at all. In fact, you're supposed to just weld it to the end of the frame.

Still waiting for proof that the oem hitches experience significant deflection that degrades ride quality, and that deflection makes them an inferior product.
