To determine your GCWR look in your printed Owner's Guide that was in the glove box when you took delivery of the new F-150. Look in the index to the Owner's Guide under "Towing" and then below that to "Trailer Towing". You should find the charts that tell you the maximum GCWR and tow rating, depending on which cab, engine, rear axle ratio, 2WD or 4WD, and wheelbase your F-150 has.

As others mentioned, the GCWR and tow rating are pretty much useless info. They are not your limiter as to how much trailer you can tow without being overloaded. Instead, payload capacity is usually the limiter, and more specifically, payload capacity available for hitch weight. The receiver hitch weight capacities without a weight-distributing (WD) hitch is the limiter on all F-150s, and the rear GAWR is the limiter for some F-150s. So assuming you use a WD hitch, then if you don't exceed the GVWR of your F-150, then you'll probably not exceed any of the other weight capacities when towing.

So forgetabout trying to tow a 9,100 pound TT with your F-150. You'll be overloaded. To determine the max weight of a TT you can tow without being overloaded remember that payload capacity available for hitch weight is probably your limiter. Payload capacity available for hitch weight is GVWR of the F-150 minus the wet and loaded weight of the F-150.

Subtract 100 pounds for a good WD hitch from the payload capacity available for hitch weight and the answer is the payload capacity available for tongue weight. Divide the payload capacity available for tongue weight by 13% and the answer is the max weight of any properly-loaded TT you can probably tow without being overloaded.

Decent guesstimates, but that's all they are = guestimates. To get a good number for payload capacity available for tongue weight to determine the max trailer weight you can tow without being overloaded, you need the actual scale weight of the wet and loaded F-150. "Wet" means full of gas. "Loaded" means everybody and everything that might be in it when towing, including DW, kids, pets, tools and jacks, campfire wood, grill and charcoal, toys, camp chairs, cooler that's in the truck and not in the camper, everything.

BTW, A Goggle search I found a trailer tongue weight hydraulic scale. Useful for me with a vehicle on a flatbed as it is required for vehicle placement on the trailer. Search for "Sherline Hydraulic scale" Ebay for $140. I will also use it on all my other trailers before I head for the commercial scale down the highway. Without the tongue weigh for my flatbed I would have to do multiple weights at the commercial scale to get it correct.

If you use a flat bed and have multiple tongue weights, why not use this?

Just curious.

Because heavy trailers need to have a weight distribution hitch. I looked close to the hitch you mention and it is not applicable for our limited tow capacity F150s. Most of us with big trailers (heavy) have to have the WDH. Of course the Sherline works with any kind of hitch.

It would be perfectly good for a light weight trailer (less than 3846 pounds). Of course that hitch costs more than the Sherline version.
You are correct your suggestion wont work for a WDH.
The limit on the hitch for a F150 has a limit of 500 pounds for a non WDH or universal type hitch. The result for 13% of the trailer weight on the hitch the max trailer would be 3846 pounds. Anything higher requires a WDH. WDH hitches are specific proprietary design that prevents using the universal hitch with the gauge you mentioned.

Probably not, because nobody makes a WD hitch with a ball mount that includes a scale. Look at the design of the ball mount part of a weight-carrying Weigh-Safe hitch, and compare it to the ball mount part of any WD hitch. The big difference is the ball mount for a WD hitch includes the attachment points for the spring bars. Without the spring bars attached, you don't have a WD hitch.

It should be no big problem for any of the big boys at Reese, Blue Ox, Curt, Husky, Weigh-Safe or other hitch manufacturers to design and produce a good weight-distributing/sway control hitch that includes a scale in the ball mount part of the WD hitch. But I've never heard of one yet.

But I need to know my tongue weight, so I carry a Sherline Tongue Weight Scale in my TT and use it often. Here's mine:

You can buy the Load Master brand of tongue weight scale for less money at Amazon.com, but I know the Sherline is good stuff and I don't know anything about the cheaper band. When I searched for "Sherline" on Amazon, the results showed Load Master but said Sherline. Confusing, so I stick with eTrailer.com

Based on the numbers you give here (AND using a WDH), you're good to go.

Your 945 lbs tongue weight falls under the 1100 lb limit.
Your payload is well within limits.

With that lined up, you should also fall within limits of your GAWR's and GVWR.

If you're really curious to know the numbers for sure, hit up a CAT scale with trailer hitch and loaded up like you're ready to hit the road. That white sticker tells you the max of your front and rear axles (GAWR) which the CAT scale will weigh for you.

If you Google it, there's also a trick you can do with a regular bathroom scale and some 2x4's to measure your true tongue weight.

But really, you don't have anything to worry about based on those numbers. Just make sure you don't load up ALL your stuff in the front of the trailer ahead of the axles. For me, since I put a heavy floor jack and my tools in a storage bin at the front of my TT, I place my XL cooler full of ice and beverages in the bathtub at the rear of the TT and also have several bundles of firewood in the bathroom as well.
