Hey guys, recently I purchased a 2018 F150 4x4 3.3L V6 PFDI 3.55 axle with 8 foot truck bed with Tow Mode. It is a fantastic truck, but during my conversations with the sales rep at the dealership, he assured me that this truck would be able to tow my 4,000 lb gross weight (hitch included) 2018 Wolf Pup trailer.

Now, I look inside the door jam of the F150 and the GCWR (Gross Combined Weight Rating) is 6,390 lbs! Of course, I discover this after towing my new trailer 25 hours to the Grand Canyon. Thankfully I purchased the 5 year/60,000 mile warranty on the truck, but that doesn't mean I want to stress the hell out of my vehicle. The GCWR also includes my 4.5 ton truck... right? So, we're basically 2,000 lbs over the limit?

This revelation is pretty upsetting to me because the sales rep on the phone assured me that this F150 would be able to tow this 4,000 lb trailer with hitch without a problem. Please tell me I'm missing something and the inclusion of Tow Mode means this truck can handle it? For the most part this truck tows the trailer with ease, although on inclines have to kick it into 3rd to keep speed. Still, it doesn't seem like this setup is stressing out the truck to an insane degree.

Thanks for any thoughts/advice here guys.

Thats the GVWR, not the GCWR, there isn't one posted on the trucks and is always a guessing game. How does it tow? OK? Do you have any issues towing? No? If those are the answers, just go and enjoy the truck. Post the white and yellow stickers and we can confirm it too.

Take that number, subtract everything you’ve added to your truck, including occupants, and divide by .13 and that is the gross trailer weight you can tow.

1500 - 200lb wife - 150lb kid - 50lb dog = 1100. 1100 / .13 = 8400lb gross weight trailer.

Now look at your gross vehicle weight sticker. Subtract your truck payload you just calculated from it (truck, wife, kid, dog), this is your truck’s weight. Subtract this from the gross combined vehicle weight and it should be around the same as above formula

Again, these are max.

Considering a Flex can tow 4500 pounds, pretty sure the OP's truck can handle a 4K trailer with room to spare.

It should be 5,000 with a 3.55 and 7500 with a 373 rear with a 3.3 v6. So Your trailer is within the max limit. Just pull up the specs.

As mentioned, that's the GVWR, which is the max the truck itself can weigh. The GCWR isn't listed on the truck anywhere; you need to look it up on Ford's towing guide. Also, your truck doesn't weigh 9K lbs.

It sounds like the sales rep didn't mislead you this time.

If he doesnt have one of the tow packages with the tranny cooler he is limited to a 5000 pound trailer. He is likely still well within his limits if he has not exceeded payload.

You guys are awesome.. what a relief! Lou, looked inside and it said weight in the truck not to exceed 1,913 lbs. Substracted my 250lb self and 200lbs in cargo to get 1,463. Divide that by .13 and I get 11,253. Minus my truck 4,400 lbs that ends being 6,853... so does that mean I can tow up to 6,853 lbs? Hoping I did my math homework right.. thanks again guys!

Checked the owner's manual, since my 2018 Ford F150 V6 3.3L is a 4x4, apparently its GCWR is 9,700 LBS. Since the truck is a 8' bed, it weighs about 4,400 lbs. That leaves 5,300 lbs for cargo and towing. Feel very relieved. The truck really does seem to tow the trailer with ease so it wasn't making sense to me that we were 2,000 lbs over our limit. Thanks again for all of the information!
