So I have a 2020 F-250 SD 4WD FX4 XLT CC SB with the 6.7PS, 3.55 e-locker, and the HCTP. (unrelated to this question but for more info, it has the 3" class V travel trailer hitch from factory rated at 21,200/2120)
It has the M275 rear axle and the 5 rear spring setup. It also has the factory Ford 5th wheel prep package.
The stickers:
GVWR - 10,800 (Tennessee rules)
Rear GAWR - 6,340
Front GAWR - 5,200
Factory cargo rating - 2,906
Factory calculated curb weight - 7,894
Actual curb weight with full fuel and no passengers (CAT Scale) - 7,780 total, 4,620 steer, 3,160 drive
Adjusted cargo rating based on real curb weight - 3,020
It is obvious that there is some significant derating going on here since the F-250 with the HCTP and the F-350 are basically the same truck when it comes to what matters towing a 5th wheel.
The Rear GAWR for the F-350 is 7,230 for the same axle and spring setup
The GVWR for the F-350 is 11,500 in the same configuration.
It appears that the limiter for rear GAWR the F-350 is the same as for the rear GAWR on the F-250 and that is the tire/wheel combo.
It appears that the limiter for the GVWR on the F-250 vs the F-350 is the artificial limit imposed by the 10,800 GVWR on my truck.
Using the non-derated numbers of the F-350, then my F-250's payload rating would be ~ 3,720.
Other notes:
Tennessee has a max GCWR of 26,000 the truck actual is 30,000
The max 5th wheel hitch capacity of the Ford 5th wheel prep package is 19,000
Now that you have all the numbers, can my truck safely tow a Grand Design Reflection 311BHS?
Brochure numbers:
UVW = 11,185
