My bud has a 90 Chev 3500 dumper that is GVWR at 11.5K and its a 90 with a 350 gasser. Where DO YOU get those figures?
I get it from the window stickers on the Fords I looked at today and what I know about trucks and GM/Ford specs on the 2011's. GM puts 9,200# GVWR on all 2500 series trucks and 9,700# or 9,900# GVWR's on the 3500 SRW series trucks. The Dually gets 11,400# GVWR. I listed the trucks I looked at as 2 F-250's and a SRW F-350.
My F-250 has 10,000# GVWR and my F-350 has 11,500# GVWR and its SRW.
Ford offers on the F-250 line a GVWR range from 9,400# on the low range upto 10,000# on the high end. There are 4 steps going 9,400#, 9,600#, 9,800#, and 10,000#.
On the F-350 SRW they offer 8 different packages with the low end being 10,200# and the high end being 11,500# There are 8 steps going 10,200#, 10,600#,10,700#, 10,800#, 11,000#, 11,200#, 11,400#, and 11,500#.
So just because it says F-250 or what ever there can be a world of difference in the capacity of the truck. Many have learned the hard way like me.
By the way the GVWR range on the F-350 Dually is on the low end 12,200# to 13,000# with 4 steps. They are 12,200#, 12,600#, 12,800#, and 13,000#.
What this amounts to is the guy doing the ordering at this dealer needs to go to school. Why would you want a HD truck without the heaviest package available? Like I said I made that mistake thinking its a 1 ton and soon learned my F-250 was more truck.
As you can see the Fords have more available GVWR across the lineup.
