I hated the duellers. I replaced them at 20k with Duratracs because they were so miserable in the snow and mud around here. They seemed like an oversized sedan tire. They were a decent highway tire and im sure they would have towed ok.

Tell what mods you have done to your truck if any? Level kit?

Agreed 100%! From a stop on wet pavement they spin like crazy, but once rolling where the sipes can do the job, they are OK in rain. I put Snow tires on during the winter as I wasn't taking any chances. My drive every day is highway, 60 miles each way, and are very comfortable and long lasting. As long as I have snow tires, I plan to replace the Duellers with another set, unless I can find other tires that ride as well, are quiet and can get 70K miles.

For now I will keep the Wranglers on and see how they handle the winter, and get a new set of 20's in the spring.

I've got a catch can hanging out in front of the radiator, Air Lift Ride Controls bags (shipping weight of 25 lbs), Bilstein 5100's. The bilsteins are set to a .75" level but my actual measured hub to fender height is basically the same as stock truck was when new. I measured it 6 months after I bought the truck and installed the Ridecontrols so that I could level the truck with the air bags when camping. I think my springs settled over the last 2.5 years.

Oh and 275/60R20 Wrangler duratracs but according to tirerack those are only 3 lbs heavier than the stock bridgestones. So I guess we could assume that 20lbs from the airbags and 6 lbs from the Duratracs extra on the rear axle.

I have been reading these posts since I ordered my truck in May of this year.

So many different contributing factors to make a truck safe and stable!

The area that made the biggest difference to me, was the tire/wheels and the hitch we use with our truck. I just changed the wheels to 18 X 9.5" (had 7.5") and it makes a big difference in how the truck drives and handles, it was also much cheaper than spending $1,000+ for new tires. Prior to the wheel changed I started by increasing the pressure to 45 PSI, a big change!

I looked up the spec's on the Ford wheels and they vary significantly, also with the different option packages, width's from 7.5 to 9.0". The HDPP's have wider spec's than others 8.5 and 9.0", assisting with the stability of the vehicle, most likely!

Discussions are fun, but facts will really help make things better.

so your point about the amount of weight on the rear axle is so far in left field. You altered your suspension obviously and then are saying in stock form a 2014 has 2,700lbs of weight on the rear axle making it better for towing then a 15+. This is hilarious!!! HELLO! McFly. You changed the amount of weight on your rear axle with your suspension mods. If i did the same to my 17 then my calculation still hold true.

This hole time you think a stock 11-14 f-150 has 2,700lbs on the rear axle?? No frikin way man.

Your attention to detail is non existant.

So since I am ordering my truck in 2 days I have a question: If I order with the Max Tow Package and then add after market HD springs along with new 20" LT tires would I be in effect maxing out my payload??
From what I can tell the only thing the HDPP does is add springs and LT tires (either 17" or 18"). It wont let me order the HDPP w/o the MTP anyway. On an XL or XLT the 17 and 18" wheels look terrible.
Anyway I am very excited...now just wonder how long it will take to get the truck after the plant fire.

Adding heavier spring to a MTTP truck without HDPP will not make it an HDPP.
Adding these heavier components will actually reduce your legal payload by making your truck heavier without legally increasing the GVWR.

HDPP adds a lot more than just springs and LT tires. Here are the components I'm aware of that are heavier than a MTTP alone:

frame rails are of thicker stock - you're not going to change this after the purchase
rear axle tubes are thicker - you could swap axles but it will cost you $$$
rear springs beefier - easy to swap
front coils beefier - easy to swap
Shocks are stiffer - easy to swap
Wheels are stronger - easy to swap if you can find some with the appropriate rating. The ones the Ford used aren't even of an appropriate rating from the wheel manufacturer. However, since they are original equipment, the law states the final vehicle manufacturer can in essence recertify them to a higher weight which is what Ford has done by putting 4,800 RGAWR on the sticker.
3.73 gears - easy to swap ( but I don't think this last one is important for the case you are making anyway)
And finally - those little stickers on the door that say what you can legally weigh aren't going to change no matter what you do.

I see. So there is more to it than what they list on ford.com. FYI I am already replacing all the factory shocks anyway, but if the rails and axles are more HD then I will just bypass the STX package and buy different 18" wheels. I know the 13,200lb max tow is kind of a phantom number. I need my payload to be at least 2200lbs..so with the HDPP and Max tow I get best of both. I get a realistic 11,400lbs of max towing. With I believe somewhere in the area of 2300lb payload. I can live with that. My trailer loaded weight is around 8700lbs..I just want maximum wiggle room and I dont want a superduty.

Thanks for the info
