According to my 2015 F150 towing guide, a supercrew 4x2 157" wb with a 2.7L and payload package and 373's, the max towing is 8,200 lb's. May need the addition 100 lbs


Edit: depending on what the GCWR is. How is that determined?

Hmm, a lightweight 5th wheel tow hauler?

I went by the Ford website, which probably had the data for the '17. Did the 2.7L lose 100lbs of towing capacity?

I like that Grey Wolf.

BTW, did you guys know Ford branded RVs? http://www.fordcampers.com/ford-toyhaulers.htm

At Ford (and I suspect at the others too) the engineers estimate the approximate GCWR based on engine power and rear axle ratio. Then they test it in the real world by tying on a trailer loaded to the estimated GCWR, then drag that trailer up a steep grade at towing speed to be sure nothing overheats and that the truck can maintain the minimum speed required. If they make it without overheating or slowing down then they add weight and test it again. After several runs over that 20+mile course, then know the actual GCWR at which that combo of vehicle and drivetrain can be rated.


Ford uses the highway between Laughlin NV and Kingman AZ at their GCWR test road.If you've ever driven that road, then you know it's a bugger dog bear.

Guess my real question about GCWR is why are two different listed for my truck? I think I have the higher one due to the 2.7 payload package.

I don't have specs for 2015, but assuming they didn't change for 2016, the 2016 Ford RV and Trailer Towing guide is not clear. For one thing, it doesn't include your truck : F-150 SuperCrew 4x4 2.7L with 157' wheelbase and 3.73 axle ratio. Back up to the shorty, and there is only one GCWR (13,300), but two different tow ratings. Since tow rating = GCWR minus the weight of the truck, I don't understand how they can have two different tow ratings with the same GCWR and otherwide identical F-150 SuperCrew 4x4 2.7L with shorty bed and 3.73 axle ratio.


For your truck but 4x2, there are actually two different GCWRs, 13,100 and 13,300. To get the higher GCWR of 13,300 apparently requires the 2.7L payload pkg. They don't provide an explanation, but my guess is the 9.75" rear end in the payload pkg provides more pulling power without overheating the diff, so they can raise the GCWR a smidgen while still meeting the SAE requirements for GCWR.

Mine is the 2wd, and I am assuming the same thing about the payload package, I do have it so would assume I am 13,300 GCWR

The 26RR is a nice trailer. I've had no issues towing mine with the 3.5 Eco fully loaded with my Atv's around 7200lbs with a tongue weight of 850-900. Unloaded tongue weight jumps up so I move heavy items to rear to offset and keep tongue weight to under 1000lbs. Fresh water is just rear of axles so if you fill it up it will take some tongue weight off too. My payload is less than yours at 1400 lbs but I carry everything in the 26RR and have never had any issues along with a decent WDH. To avoid some bounce I did add airbags and load E rated tires to the Eco. Really impressed with how easy the trailer pulls. Hope this info helps.

For a tandem-axle travel trailer, GCWR of the tow vehicle doesn't matter. So whether it's 13,300, 13,100 or 12,000 doesn't matter. You cannot tow a trailer that grosses anywhere near 10,000 pounds without exceeding the payload capacity of your F-150. So concentrate on GVWR and payload capacity of your tow vehicle, and don't worry about the GCWR and tow rating.

If you need to tow a wagon-style trailer that has almost no tongue weight, then GCWR might be useful for matching trailer to tow vehicle. Wagon-style trailers are used for hauling grain such as wheat, milo, or corn from the field to the elevator. The GCWR tells you the maximum weight of the tow vehicle and loaded trailer you can tow without overheating anything in the drivetrain and without being the slowpoke holding up traffic on hills and passes. So if you don't exceed the GCWR of the tow vehicle, you know you can pull the load. But the limiter is not how much load you can pull but how much hitch weight and other weight your tow vehicle can carry without exceeding the payload capacity of the tow vehicle.

For example, my F-150 has GCWR of 14,000 pounds, but it's overloaded when grossing 11,400 pounds with my TT that grosses less than 5,000 pounds. On one trip dragging a small 5er, I grossed 14,780 pounds, but I was overloaded over the payload capacity of my tow vehicle by 880 pounds. No problem PULLING that trailer, but the tires and suspension of the tow vehicle were crying UNCLE!
