Hi, and welcome to the forum!!


I assume you have a tow package that includes a trailer hitch and the ITBC (the Integrated Trailer Brake Controller).


First of all, look at the stickers on your driver's side door. There are two stickers - one has the GVWR and GAWRs for your truck; the other is a tire sticker with some yellow on it, and says something like "weight of passengers and cargo can never exceed xxxx lbs" (which is the "payload capacity").


The payload capacity will likely be the most limiting weight for towing. It is the empty weight of the truck (empty except for a full tank of gas) subtracted from the GVWR. So, anything you add after your truck was built (bed liner, tonneau cover, etc.) will have to be subtracted from the weight published on that sticker to know what you can really carry.


The payload capacity includes people and cargo in the cabin and bed, plus the weight of your WDH (Weight Distributing Hitch) head and the tongue weight of your wet & loaded trailer.


The tongue weight must be 10% to 15% of the loaded trailer's weight, with 12% being a realistic number.


If your trailer wet&loaded weighs, say, 7000 lbs, the tongue weight should be around 840 lbs. If your WDH head weighs maybe 60 lbs, then that 900 lb total goes toward using up your payload capacity.


Also, lie down under the rear bumper and look up at your hitch and you will see a sticker with the hitch rating weight limits. With a 3.55 rear end you don't have the max tow package, so it should read 500/5000 (tongue wt/max trailer wt) for towing without a WDH, and with a WDH it should say 1050/10500. You should be well within those limits.


If you have, as an example, a payload capacity on your sticker of 1400 lbs, then subtract the 900 lbs your trailer is going to use up, and you have 500 lbs remaining for people and luggage in the cab, and maybe some firewood, a jack, and some tire changing tools handy in the bed.


Bottom line - You'll need to know the payload capacity for YOUR truck, how much the weight of people and cargo will be when you're loaded up for towing, and make sure that between the tongue weight and weight of people and stuff in the truck that you aren't over the payload capacity.


Then you need to take the rig to your local CAT scale make sure you know exactly what you weigh so that you know you'll be able to tow comfortably and safely. You'll be able to see what the weight is on each of the truck's axles to make sure you're not exceeding either the front or rear GAWR.

Kodi's way better at explaining this stuff than me. I concede good sir

What Kodi said. Your most restrictive weight limiter is the GVWR of your F-150. Next most restrictive is probably the rear GAWR.

My guess is you'll probably be overloaded over the GVWR and maybe even the rGAWR of your F-150. My F-150 is overloaded with my TT with GVWR of only 5,600 pounds that grosses only 4,870 pounds when wet and loaded on the road. Your TT will have a lot more tongue weight than my 650 pounds.

You asked, "Am I gonna have any problems towing that much weight ?" The answer is no, you have a powerhouse drivetrain that can pull that wet and loaded trailer with no problems, other than overloading the suspension of your F-150 over the GVWR of the truck. My similar EcoBoost drivetrain with 3.15 axle ratio has no problems pulling an 8,000-pound 5er across the Hill Country, but the poor little F-150 chassis is severely overloaded over the GVWR and rGAWR of my pickup when I rarely tie onto that 5er.


Here are my weights when moving that 8,000-pound 5er from Austin to home through the Texas Hill Country:


3300 Steer axle (3650 fGAWR)
4680 drive axle (3,850 rGAWR)
--------
7980 GVW (7,100 GVWR)
------------
6800 Trailer axles (7,000 combined trailer GAWR) (1,200 pounds pin weight = 8,000 pounds trailer weight)
--------
14,780 gross weight (17,100 GCWR)
========


So nowhere near the GCWR or the 8400 tow rating of my F-150, but severely overloaded over the rGAWR and GVWR of my F-150.
