Actually what I stated is exactly why they do it. But, we're splitting hairs. They don't need a separate class of truck when you can already order a 350 SRW derated to 10k. Make the GVWR a package choice on the 250's like they currently do on the 350 SRW's and it would make more sense.
As to the new Ram's, as of 2015 the 2500's are completely different suspension than the 3500's using coils in the rear.
No it is not. Ford cannot option a Class 2 F250 to have a higher GVWR than 10,000 lbs because that is the max GVWR you can have in that class. A GVWR higher than 10,000 lbs would put it in Class 3 which is where the F350 is. Most states require special licences or a higher registration to operate a 10,000 lb and up GVWR vehicle. These are the main reasons why Ford and other manufacturers derate there 250/2500 trucks.
This is also why the payload is so low in diesel 250/2500 trucks. Since payload is curb weight minus GVWR and the heavy Class 2 250/2500 diesel trucks are capped out at 10,000 lb GVWR, then their payload rating is derated by a huge amount to make the truck fit into 10,000 GVWR. Going by the actual component ratings of the diesel 250/2500 trucks, they should have a payload of about 1,200 lbs more, but that would put them over 10,000 lbs GVWR which is where class 3 350/3500 trucks already are.
