I'm confused and need some input from those in the know. I just bought a 2018 F150 Subercab XL. It has the 2.7L 6cly Ecoboost and 6400# GVRW pkg. It is a 10-sp automatic/w tow mode. Can anyone tell me what the tow rating is on this? I have found/been told conflicting numbers and would like to buy a travel trailer. I don't want to surpass the capabilities of the truck. It is a 4x2 w 3.73 axle ratio

 

According to the 2018 Tow guide, not knowing if you have the 145 inch or the 163 inch wheelbase version of your SuperCab nor if you have the "2.7 EcoBoost Payload Package" or not, the guide says 8,200 lbs. It could be as high as 9,000 lbs or it could be 8,300 or 8,400 lbs, all depending upon the exact build of your truck. I'm basing this off of the description of your truck being a 2.7L GTDI SuperCab 4x2 with the 3.73 axle. So to be on the safe side, go with 8,200 lbs unless you have info that bumps that number up a bit.

I looked at a dealer's 2018 blog and if yours is a 145 inch WB, being that you have said you have the 6400 lb GVWR, you either have an 8300 or an 8400 lb towing capacity. The difference between those two probably is the EBPP for the extra 100 lbs. Safer to go with the lower (slightly) rating unless you're absolutely certain you've got the appropriate package.

Without knowing more, I'd even say to go with 8,000 lbs to be safer, unless you definitely have the 145 inch wheelbase truck, which you haven't said you have or not.

 

Thanks, akulahawk...I definitely have the 145" wheelbase. I really appreciate the info. That's what I was hoping for!
I'm brand new at this, a single lady trying to learn about trucks...I may ask some stupid questions. I apologize in advance!

 

Towing capacity is not all that pertinent for the purpose of towing a travel trailer. Your limiting factor will likely be the payload capacity of your specific truck.

Look on the driver's side door pillar for the yellow/white Tire and Loading Information sticker. What does it state the 'the combined weight of occupants and cargo should not exceed xxxx lbs....' weight is?

From that figure you can develop a baseline for the true loaded travel trailer weight you can safely tow.

 

This ^^^

Don't look at the towing guide, and don't look at blogs. Read the tag, and then read the dozens of threads that run through the numbers.

 

Don't be afraid to ask questions, you have come to the right place. RV salespeople will get you upside down in a hurry, they are not a good source for technical info. As mentioned above, Yellow sticker in your Drivers door, what does it say as carry capacity. Attached is mine for reference, means my payload is 1760. It will help us advise you what is the most you can do. As a general question, what type and size trailers are you thinking? Travel trailers range in size and weight. If you are thinking 19' and 4000#, no problems. Bigger... what are you thinking?

 

No worries, everyone has been brand new.
Out of curiosity how big a trailer you thinking about?

 

It's the 6400 lb GVWR that is going to limit you. You won't be able to tow anywhere near 8000 lbs with that. A 8000 lb trailer along with a WDH will put about 1200 lbs on your truck's suspension. Check your payload. Even with a 1700 lb payload that only leaves 500 lbs for the driver, passengers, and cargo in the truck.

 

This is the bigger problem/issue with our class of trucks. We'll run out of payload typically before we approach the rated tow weight. OP, you'll have to be EXTREMELY careful about how much tongue weight you'll have on your truck as well as how much total weight of the entire combined rig is. Too light on the tongue and your trailer can get VERY sketchy, if not downright dangerous, in handling while towing. Too heavy and you'll overload your suspension and that's not good either.

That being said, as long as you plan your towing to the payload capacity of the truck, you'll have PLENTY of margin of safety for what your truck can tow. My truck is rated to tow 11,500 lbs. Payload available could potentially limit that to under 9,000 lbs. I'm not planning on towing anything heavier than about 8,000 lbs so... I will have a decent safety margin. OP, at 8,000 lbs, your truck will likely be reasonably close to what it can do safely.

 

It's dark now, so I will look at the sticker in the morning. I was thinking on the lines of a 22-24' trailer between 4-5000# dual axel trailer. I will be traveling alone and only weigh 125#. My travel partner is a 37# dog. I will tow the trailer dry, and not fill it full of "stuff"
