You would think, but the payloads are all over the place on new stuff. I think you can get an F150 with a payload over 3000lbs. I was going off GVWR.
Long RANT
In theory, it is possible to get an F150 with payload >3k lbs/GVWR >7,850 lbs, GAWR F 3,400lbs, R 4,800lbs. But that requires:
Regular Cab Long box 4x2 with HDPP (Heavy Duty Payload Package - which includes heavy frame, 18" LT tires & 9-3/4" rear axle).
It has to be an XL, with:
Manual Door Locks, Mirrors & Windows
Just AM/FM radio and the 2.3" infotainment screen
Trailer hitch & Cruise delete
Small gas tank - empty (filling the tank adds ~120lbs/takes you under the 3k number)
(at least you have to have the 3.5 Ecoboost or 5.0)
Note: No driver and/or passenger(s) - they are considered part of payload.
And the rims are only rated for 2,275lbs so GAWR R should be limited to 4,550 lbs.
Has anyone seen a '15 or newer F150 with Manual Door Locks, Mirrors & Windows?!
Aside: my '17 RCSB F-150 is over GAWR F, with me, my son and full tank. Only non OEM component in that is the floor mat We aren't significantly over the weight of 3 x 150lb "standard" occupants, so I don't know what Ford was thinking when they spec'd/built it.
The towing number is a similar fudging.
While
@Jim Oaks' 2016 Ford F-150 Crewcab 4x4 has a 'brochure' number of 10,600lbs, that assumes:
Jim + significant other weigh <301 lbs combined (J2807 spec at requires both driver and passenger).
The F-150 has HDPP (7,850 lbs GVWR) package.
A non-HDPP loses 800lbs+ in GVWR/>500lbs in payload*. So, a non-HDPP F-150 has towing limit about 5,600 lbs (2807 requires 10% tongue weight on trailer). This assumes the non-HDPP has the trailer tow package with 9-3/4" rear axle. (And the extra weight of the 9-3/4" hurts payload)
*Many non-HDPP trucks aren't configured to the max GVWR possible for their configuration/are fancier than XL/have aftermarket accessories (bigger tires/grill guards/etc) and often have more than just one passenger/driver & passengers are >300lbs combined)
My son's company rents him F-150 SuperCrews on regular basis - most are <6,400 lbs. GVWR, GAWR R - 3,300lbs, so payloads are <1,200 lbs. By the time you have 4 - 200lbs guys in the cab and couple hundred pounds of gear in the box, the truck is at GVWR! Towing a trailer isn't possible as the truck doesn't have any payload capacity to take the hitch weight.
I have the opposite issue with the camper/trailer guys - seems like brochure weight was for the CAD model; the actual numbers are way higher, especially tongue weight which are significantly over 10% (brochure weight doesn't have propane tanks and/or batteries which are often at front of trailer and their weight adds directly to hitch and trailer needed to be >10% without them to be stable.)
As a result, a lot of F-150 owners lose their minds when they get busted for being overweight when they knew they were under the brochure numbers.
My '99 Ranger might have a max possible payload of 1,560lbs in the brochure, but with 4.0/auto/8.8/XLT/Payload pkg #1/full tank gas/me, the real number is <750lbs. (Payload pkg 1 reduces max from pkg #2's 1,560lbs to 1,260lbs). The '99 Ranger's tow number was pulled from a hat after reading the '98 S-10 brochure.
The current Ranger's tow number is similar - for an XL with no options and nothing in truck but driver and passenger.
