They can't? They certinly come close to it.
The trucks with highest payloads are RegCab 4x2s
Compare their base rear axle curb weights to rGAWR.
This was sent to a Car&Driver reporter from Ford and posted as part of their 2015 F150 review. Only the 4x2 2015 data was sent AFAIK.
The only 3300 lb payload I see shows a reg cab 2wd that has a rear base weight of 1843 lbs. Add the two gets us a 5143 lb which is a overload on the 4800 RAWR which is my point in my reply to redracer.
The problem is Ford/Dodge/GM payload numbers on the stickers come from a GVW minus the GVWR calculation. That math doesn't take RAWR into consideration.
I've never used payload sticker numbers as most trucks out here don't have one. I only became interested in the payload discrepancies the last couple of years when some folks mostly with gas powered trucks complained about exceeding their trucks RAWR but was still under GVWR.
Anyhow...Thanks for the new specs as the new F150 spec sheets hasn't shown up on Fords Fleet page website yet. Looks like Ford dropped the 8200 GVWR package for a 7850 GVWR but kept the 4800 RAWR.
