Omg. You aren't not kidding. I can thank you enough for the reply. A lot of that makes sense. There are a ton of factors. So based on that I did find some charts. Based on what you said this seems to be pretty accurate I would imagine I still need de deduct passenger, food, water, gas,dogs ect off this number?

So with my 5.0 Supercrew 14,300 145 Wb is it safe to say 8,900 towing. And then when I load my *** in it I subtract the weight?

I'm just a simple guy and that is a bunch of math. I'm sure like most people figuring out what gene did is very dificult. It may be the only way but I'm sure most people like me won't be pushing it to the max. I'm just wondering what she can tow so I stay away from that number.

So far this forum has been awesome. Thanks guys.

Those "tow ratings" are misleading. They are simply GCWR minus the weight of the unloaded truck. So they tell you the maximum trailer weight you can PULL without overheating anything in the drivetrain, but they ignore the weight you can CARRY on the suspension and tires of the tow vehicle.


Hitch weight will be your downfall. Your truck can pull a lot heavier trailer than it can carry the hitch weight of that trailer without being overloaded.

So the simplest way to determine how much trailer you can tow is to load the tow vehicle with all the options, people, pets, tools, campfire wood, and everything else that will be in it when towing. Fill up with gas, then weigh the wet and loaded tow vehicle.


Subtract the weight of the wet and loaded tow vehicle from the GVWR of that vehicle, and the answer is the max hitch weight you an have without being overloaded. Subtract 100 pounds from that max hitch weight, and the answer is the max tongue weight of any travel trailer you can tow without exceeding the payload capacity of your tow vehicle.


Compare that max tongue weight to the max tongue weight rating of your receiver hitch. Use the lighter weight of hitch limit or payload capacity limit to determine your actual max tongue weight limit.


Divide that max tongue weight by 0.13 and the answer is the max weight of any TT you an pull without being overloaded over the payload capacity and receiver hitch capacity of your tow vehicle.


Yeah, it's slightly complicated, but towing a trailer without being overloaded is serious business, so spend the effort required to get it right.

Actually it's a good calculator. It will provide you with the weight of the trailer if you plug in the trucks info.

"For most tow vehicles, if you don't exceed the payload capacity of the tow vehicle, you won't exceed any of the other weight limits of the tow vehicle"

You can't say that about these new trucks. The payload is a lot higher than the previous 2015 models.

If I go by just the numbers, I will void the warranty if I tow a trailer over 5100 #s as per the owners manual and Ford's towing guide.

If you follow my logic, you will see that gross payload capacity of the truck is not part of the calculation to determine max trailer weight. I said "subtract the weight of the wet and loaded tow vehicle from the GVWR of the vehicle and the answer is the max hitch weight you can have without being overloaded."


Yeah, that max hitch weight is actually the payload capacity available for hitch weight. But when you use the words "payload capacity", some folks get confused and assume the payload capacity on the yellow sticker is the max hitch weight they can have. So they wind up overloaded.


And yeah, the '15-up F-150s are lighter than the previous generation, so they have higher payload capacity available for hitch weight.


The CAT scale doesn't lie. When you cross the scale with a wet and loaded TT, and add front and rear axle weights to get GVW, then compare GVW to GVWR you'll know if your estimates of weights was good enough to prevent overloading. Folks that use estimates instead of scale weights are often going to be overloaded when they finally weigh the rig.

J2807 SAE Towing Standard

4871 lb +1% = 4920 lb (Ford's worse case Curb)

4920 + 11 lb (53A Tow Package) = 4931 lb

4931 lb + 150 lb (Driver) + 150 lb (Passenger) = 5231 lb

Trucks below 8500 GVWR do not have a weight allowance for WDH and other additional equipment.

14300 - 5231 lb = 9069 lb

Ford chose to rate the truck with 169 lb Reserve Capacity
.
If your options and accessories over a stripper base truck of the same cab, wheelbase and drivetrain add up to less than 169 lb and you have less than 300 lb in driver and passenger you can tow 8900 lb.

Edit: Of course in the real world you would still have WDH weight to account for

Ford has done a pretty good job of making the towing guide a good place to start. The guide says that I can tow 9100 pounds. The problem is all the junk we have to take with us.

My truck weighed in at 5140 #s on the cat scale. Full tank of fuel, tool box with emergency equipment, no driver or passenger. Add all the junk and bodies, now I'm up to 5840 pounds.

14200-5840=8360

8360*13%=1086 tongue weight. To much tongue weight. I need to be about 960 pounds to keep me at gvwr. So I figure I'm ok with a 7300 pound trailer, not 9100.

Hopefully folks take the numbers from the guide and do read the fine print.

Now I know I can adjust the tongue weight with a little manipulation of weight in the trailer, but I prefer not having to do that. It's a real pain to having to tell the wife where she can put stuff in the trailer.

If[QUOTE=msgtord;5192645]I understand completely. I just get a bit aggravated at guys who want to use a flat 13% for tongue weight and Assume ever truck starts at 5700 lb curb and weighs 6500 lb before the trailer ever hitches.

I'm at 6000 GVW at 12500 GVW with 600 lb in the truck, a 800 lb hitch load (includes WDH) and a 7000 lb trailer. I do have the advantage of an very effective WDH but to hear these guys you would think that would be impossible.

PS I do have one question. Am I supposed to count ball and mount weight toward hitch load? I've been counting the WDH toward the hitch rating but just realized I haven't counted the ball and mount. Not a big issue because I've got 300 + lb to play with.
