I stopped by a Ford commercial dealer to inquire about a f250 truck they had and got to talking to the sales guy. I specifically brought up the f150 and HDPP and he immediately stated the following.

“ the HDPP does not in anyway increase the towing capacity of the truck. It’s primary purpose to increase the capacity of the truck stand alone not when towing “

I’m sure a lot of you know this already and he went on to say that the max towing is what is stated in the towing guides no more. So a f150 screw 5.0l with HDPP with a fifth wheel rating of 10,500 its max pin of 15% is 1575lbs. Anything above that pin weight is not SAE compliant regardless of payload rating and RAWR and would void the vehicle limited warranty. Now having the HDPP will surely help with adding gear and passengers in the truck so it does have its value. The f250 they have is an odd XLT w/packages 4x2 CCSB with 4.30s for under $42k. I have a family member that’s probably going to jump on it for towing a TT.

Never listen to a salesman as they are just that, salesmen. They have no training related to understanding what they are selling.

To state that the HDPP is stand alone is in error. As stated over and over again here, payload is the primary limiting factor in towing. Almost all trucks will hit payload capacity before their towing capacity. The increased payload will allow for a higher tongue or pin weight, which is part of your payload.

The tongue or pin weight is supported by the payload of the tow vehicle and becomes part of that total.

It would seem this is another salesperson who does not fully understand the vehicle they are selling.

I guess I dont understand where the 1575 lbs come from. Is this similar to the slide-in camper payload capacity which states there is to be a 150 lb person in each seating position? That chart also suggests a 1585 lb payload for a 5.0 screw HDPP assuming 5-6 people in the truck.

Or are you simply taking the 10,500 lb rating and multiplying by 15%. If that is the case then the conventional towing is the same way in that it can only include a 10% tongue weight which we all know is not true. Also, if a 3.5EB HDPP truck is rated for 11,700 then it can do 1755 lb pin weight?

I disagree he was very knowledgeable, this was a heavy truck dealership not a car dealership. If a HDPP truck could handle 2000 lbs pin that’s 15% of the trailer the ratings would be 13,500lbs. Sorry it’s only SAE j2807 compliant at 10,500 and 1,575 pin.

The SAE tests for fifth wheels states a 15% pin weight. 15% of the 10500 rating is 1575. That’s with 300lb of passengers in the front during the test.

Yes with the 11700 fifth wheel rating it should have been tested at 1755 lbs pin weight.

Just remember that these SAE tests are very controlled with near perfect weight distribution and CG. It doesn’t always work so perfectly in the real world.

We are not talking about tests here but his statement that payload is stand alone and not related to towing a trailer. It most certainly is related in a very important way.

He stated that the “primary” purpose of the HDPP was to increase the capacity of the truck stand alone. Such as a slide in camper or contractor with people, material, and tools. It certainly does help when towing no doubt.

Ok so its not SAE complaint but does that mean its not legal? If I were to have an HDPP and loaded it with a 2000 lb pin, but stayed at/below GVWR, GCWR, and GAWR's, would a cop at a weigh station be able to tell me I cannot continue and need to come back with a more capable truck? As far as I knew, J2807 is simply a guideline for the MFG's to follow so they cant make outrageous towing claims without justification. I cant see how staying within the published GVWR/GCWR/GAWR but exceeding 1575 lbs is an issue.

The warranty thing is totally irrelevant in my eyes. how the hell is ford gunna know you exceed 15% pin weight unless you roll up to the dealer with the trailer and a Cat-Scale print out and hand it to them, effectively throwing yourself under the bus. No different than somone taking their stock truck to the drag strip and trying to do a boosted 4x4 launch in an EcoBoost and blowing up the transfer case or something.
