Not even close to enough information to say yes or no.

Search the forum some, do some reading then come back /w a bit more info and ask.

You may be OK but check here

If my eyes did not cross on me it looks like loaded you are good for a little over 10,000 in a rear hitch towing set up and or 5th wheel. You have best towing engine thankfully and it even is stronger than the Power Stroke offered in the 2018 F150.

what's the payload capacity? it's on the driver's door sticker. it'll say "Occupants and cargo should not exceed xxxxlbs."
and i doubt if you have the Max Tow Package, with a 3.15 ratio. that's a gas mileage ratio, not a towing ratio.
my guess is that a 8400lbs trailer is TOO much.

According to the Ford towing guide max towing /w that configuration would be 10,700 https://www.ford.com/resources/ford/general/pdf/towingguides/17RV&TT_Ford_F150_Sep7.pdf

You will hit another max before you get anywhere close to that 10k number, either payload, Rear Axle Rating Hitch Rating or just the amount of weight you feel comfortable /w behind an 1/2 ton truck. As stated about six billion times that published towing weight is just what the truck can pull, it does not take into account what the trucks suspension can haul.

Whats your Payload?
Is that 8400 Dry or Loaded?
Have you measured tongue weight?
What towing package does your truck have? With a 3.15 axle it wont be max tow, but do you have any tow package at all?

Lets start there

8400lbs dry or loaded?

Please feel free to read through any of the 40 threads on this opening page to learn how to figure out your specific capacity (as it's pretty much broken down in every single thread in this section )

You should have just over 10k tow capacity with those gears depending on exact options. The problem will be your payload. Any added weight from tools, occupants and even big gulps. Check your door sticker. After the tongue weight of the trailer is added to the truck you will not have much capacity for passengers, big gulps and their gear is what usually happens.

Hi, DM, and WELCOME! to our campfire.

Assuming the wet and loaded weight of the trailer, or the GVWR of the trailer, is 8,400 pounds,
and assuming your F-150 also has a factory optional trailer towing package,
and assuming you will tow that trailer with a good weight-distributing (WD) hitch,
your drivetrain can PULL the trailer over hill and dale without overheating anything in the drivetrain.

But if you don't have a Factory trailer towing package (order code 53A, not just the hitch which is order code 53B), or if that 8,400 pounds is the dry weight of the trailer, then your F-150 will be toast.

And if you try to tow that trailer without a good WD/sway control hitch, you could be upside down in the ditch halfway through the trip.

Even with a trailer towing pkg, with a max wet and loaded trailer weight of 8,400 pounds you will probably be overloaded with any weight in the F-150 more than a skinny driver. The normal F-150 loaded with a small family and tools and stuff will exceed the payload capacity with that heavy a trailer. 8,400 gross trailer weight will have hitch weight of about 1,200 pounds. Subtract 1,200 pounds from your payload capacity and the answer is the max weight of all the people, pets, tools, toys, and other weight such as campfire wood you can have in the pickup while towing.

As others have suggested, I and others have explained this in great detail in other threads, so take their advice and read some of those threads to give you a better idea of how to determine the max weight of any TT you can tow without being overloaded.
