Default What's my GCWR?

Just ordered a new 2019 King Ranch 4X4 with max tow, 157" WB and 20" wheels and 3.55 gears, the order sheet says GVWR 7050#, trying to figure out what my tow rating is. Dealer told me it's 13000, but it drops of with the longer bed to 12900. I'm a little confused and I want to make sure I get the towing capacity I need. I tried to make sure it had the heavy duty payload package, but he couldn't find where to add it to the build sheet. Any body have some insight? Thanks

If it is a 3.5 Ecoboost it has 18,400 GCWR with the max weight of the trailer being 12,900.

It will have the 3.5 EcoBoost, sorry I failed to mention that, I figured it would be 18400 but I just wanted to be sure and knew I could get a straight answer here. Thanks

Nope, wrong, thats not how to find out the GCWR. Payload is the way to find it. Rough estimate your payload will be 1570 pounds. That limits you to roughly 8300 pounds of trailer at 13% tongue weight. That truck is more likely to be 15350. Those published GVWR are base on XL trims with the proper options. Payload becomes the deciding factor for all others.

There is one possible way to actually tow the published weight and that is if you tow a 4 flat trailer that uses a tow bar, like a hay or grain hauler, and maybe a boat at 7% can be towed, then you could reach the 18400. . In all other cases, it depends on tongue weight.

You don't see the GCWR listed much anymore. The number you need to pay attention to is the GVWR of 7050. That is the total weight allowed on the truck including tongue weight from the trailer. There will be a payload sticker on the door too. I don't know if you can find that number before the truck physically comes in. But basically they subtract the actual weight of the truck when it leaves the factory from the 7050 GVWR. The difference is your payload. Every truck is different depending on the options you select, but typical payload is 1600-1800 lbs. The higher trim level trucks like King Ranch are heavier trucks which cuts into payload. And any modifications that you make to the truck, or tools, etc that you keep in there also eat into payload. It is a good idea to actually weigh the truck after you get it and put everything in/on it that you plan to keep on it then subtract that number from GVWR to find your true payload. I have a cap that weighs about 200 lbs that reduces my payload by that much.

I wouldn't be surprised if it is less than 1600 lbs. A 13,000 lb trailer, plus the required weight distribution hitch will put about 1800 lbs on your tongue. With most trucks you're overloaded before you include the weight of the driver, passengers or cargo in the truck. The 3.5 engine and 3.55 gears will easily pull the 13000 lbs, the problem is payload. An XLT will have a little better payload, 4X2 is about 200 lbs lighter than 4X4 and the regular cab and supercabs are lighter which increases payload. The 5.0 engine is a little lighter than the 3.5. All of those add up. The above estimate of about 8300 lbs max is probably pretty close to accurate. But it is impossible to say for sure without the payload.

The HDPP would give you another 800 lbs of GVWR getting it to 7850. If you do that it gives you more usable payload. But I still don't think you'll be able to pull 13,000 lbs unless you load the truck pretty light. But it should get you a lot closer.

Wow that's a lot of info to process, my trailer is roughly 9620lbs max with a hitch weight of 820lbs. I typically don't max out the trailer and we don't put a lot of crap in the bed of the truck when going camping. I'm just a little concerned with not having enough truck to safely tow my travel trailer.

If the GVWR of the camper is 9620, you will be fine.

If you only have 820 pounds on the ball with that heavy a trailer, unless it's a boat, it must me one hell of a tail wagging biotch, that's less than 9% tongue weight, well under the 10-15% required.

yeah, that is not much tongue weight considering how big the trailer is. i think your truck will do fine pulling it

Interesting that the 20" wheel requirement dropped off those towing charts for 2019. I'm used to looking at the 2018 charts, which required max tow and 20" wheels to achieve the highest tow rating. They also dropped 100 lbs off of the 4x4 157 wheel base configuration for that engine / gear combo with max tow. Not that it really makes a difference in the real world use case.

GCWR shouldn't change based on your trim level or options, but your available payload will. The King ranch will have less payload than an XL or a truck with less included options. That few hundred pounds difference can turn into a few thousand pounds of real world towing difference. Just keep that in mind as others have explained.
