Trying to figure out the towing numbers on the truck I've just purchased - 2018 F150 SuperCrew 157", 7050# GVWR package, 3.55 axle, Max Trailer Tow Package. Payload label states mac occupant and cargo as 1732#.

Confusion lies in the owners manual for me. First, they label the cabs as Single, Super Cab and Crew Cab, vice SuperCrew - I believe the SuperCrew is covered in the manual as the Crew Cab. If that is correct, then it states a 18,400 GCWR when equipped with the Max. Duty Trailer Tow Pkg Class IV hitch. Is that package referred to as the Max Tow Package on the Window sticker?

If the 18400 CGWR is correct, then I see a curb weight (full fuel, no cargo/occupant) as 7050-1732=5318# , therefore max trailer of 13082# (minus occupants and cargo, not accounting for the transfer of tongue weight from trailer to cargo, etc, etc).

Do I have those details correct? Not trying to suggest It's optimal to use every pound of the capacities, but want to have them correct as a starting point.

 

As others will chime in with a better explanation, payload will be the biggest limiting factor when considering what size trailer you can tow. Even though these F150s say you can tow upwards of 12K lbs, you will quickly find that you can really only safely tow trailers well below that number.

 

If it was me, I wouldn't bother to even look at GCWR, the chance of you going over the combined weight rating before you hit the GVWR is basically zero.

You have a good amount of payload to play with, what does the sticker on the hitch say for max weight carrying capacity? What will you be traveling with while towing? Family of 4 you by yourself? Anything in the bed? Answer those questions and we can get you started.

 

Agreed. Based on the above number being correct and a 13% tongue weight, I show 4 adults in the ruck (1000lbs) as reducing the trailer weight to 5630lbs due to the 732lb tongue weight plus occupants maxing out the truck capacity for cargo. Whereas only 1 pers @ 250 lbs would leave you with a max trailer of 11400lbs.

 

I stated the bounds of the problem in the first post. You are correct that occupant/cargo weight will be the essential limiting factor in the max trailer weight.

What I need to know is if the numbers I found in the manual are correct given the confusion of tow package names and cab type names in the manual.

 

I just crawled under the truck, and other than a white sticker with a part number and QR code, part number HL3A-19a478-BA, there isn;t a sticker with the usual weight capacity numbers that I'm used to seeing. Frustrating.

 

Cornerz, all of your numbers are correct.

If you are asking how Ford gets to their tow rating, their numbers are based on 10% tongue weight. Your numbers are correct based on 13%.

 

Are you in Canada by any chance?

 

Hmm, another one without a sticker. If you have Max Tow package, the receiver is rated 1320/13,200. What you can do to know how much trailer, then load it up with people and stuff and a full tank and hit a scale. Subtract that weight from GVWR, and divide by .13 to get the trailer weight.

So if you have 1400 pounds left, then 1044 / .13 = 10,769

 

I am.
