I have been looking at a F250 Diesel with 17" wheels the door sticker states Front GAWR 5940 Rear GAWR 6100 and the GVWR 10000 is this good enough to tow FW around 9000 to 11000 lbs?
I don't know what year your looking at I thought the standard wheels were 18", I know mine has 20"
Honestly if I were to be truck shopping knowing that my intentions were to tow a 5th wheel I would just skip over to a 350srw as that will give you 11500 for GVWR
