Fun thread. one of the biggest gains in the HDPP is the semi-floating differential. Iím pretty sure all frames are the same. Since th OP said they have a 6 1/2 box, that means they have a crew cab, and yes, you can have the 3.5 twin turboíed ecoboost engine. With a crew cab the cargo capacity should be at least 2300 lbs, maybe more depending on options. The OPís fiver has a listed pin weight of 1185. Add say, 200 for the hitch, and they have approx 1k for passengers, fuel, and ďstuffĒ. Totally doable. Ford discontinued the 7 lug wheels a while back, so I think the brakes are the same, but Iím not 100% on that. Regardless, the fiver has brakes that are meant to stop itís weight. Hereís an actual sticker from a Scab 8í box XLT HDPP. Note the 2524 capacity THATíS MORE THAN JUST ABOUT ANY F250 DIESEL. The OP is fine.

RV brakes are intended to stop the trailer.

In its towing guide Ford states vehicle brakes are intended to handle GVWR and not GCWR and recommends towed vehicles have brakes. Evidently tow vehicle GCWR is connected to the ability of the drive train to pull a certain weight not ability to stop it. That the GCWR changes with gearing indicates that.

Ford uses three different frames for the F150 according to Fleet Ford specs.

sidewall rails..........................Section Modulus (cu in)
9.06 x 3.58 x 0.87 (LD)..............4.95
9.06 X 3.58 X .100 (HD).............5.73
9.06 X 3.58 X .110 (HDPP)..........6.28

.................................................. ...........................

Brakes are a function of the vehicles FAWR and RAWR at a minimum.


GCWR braking is the sum of the truck and trailers axles ratings at a minimum. GCWR isn't placarded on trucks at this time.

Ford shows a 13.8" front brake rotors.

And a 13.23 dia and a 13.75 dia rotor for the rear.

Leo, bold assertions and exclamation points aren't cogent arguments.

Rotor sizes are only a part of it.

What's the loaded pin weight on the 5th wheel? The lightest unloaded pin weights I have seen are around 1200# on a 9900# gvwr 5th wheel. Add 10% (low estimate) and the pin weight is now 2100#. Now add 5th wheel hitch kit and just the driver and a passenger. So about 600#. Payload is now exceeded on the F150 in your picture. Personally, I don't care if you want to pull a 5er with a half ton truck. It's your money and your family's life being gambled with. I'll pay "too much money" to buy a truck that will do the job right and safely.

And there are states that the GCWR determines the type of license you need to drive your RV (non CDL) so saying that number doesn't mean anything is ignorant. Good luck arguing that with the DOT police or your insurance company when they deny you coverage in the event in an accident regardless of who was at fault because you were overloaded.

Been watching too much btbrv or lissening to someone that watched that clown too much. Gcwr does not determine your license requirements, its the gross rating of the truck and trailer combined in most of those instances. It works the same way with a cdl.

No cdl until combined ratings are over 26k and then your trailer weight determines if you need a or b. > than 10k on the trailer needs an a. A 36k truck and 8k trailer only requires a b. A 19k truck and a 19k trailer requires an a. As far as what you can legally tow gcvwr means nothing. Its a warranty number, nothing more.

Point taken.

OTOH, if you are standing on the railing of the Bay Bridge and ask if you think it will rain, lots of us would get distracted.
