Well Mike, IMO, this 250 will work, if you stay under RAWR/tire rating. A 250 is class rated on GVWR, even if orderd with the 350 suspension, like mine. When you add the heavy diesel engine, it takes away from the class rated GVWR. The 250 payload on tire loading sticker is the weight of the truck, when it left the factory, subtracted from the class rated GVWR.
The pin weight of the FW will be almost entirely on the rear axle, so RAWR, and tire rating are what really matters on a 250. The front axle has the heavy diesel weight covered. In many cases a late model 250 can do the same job as the 350 SRW. If the 250 rear springs are a little soft, you may have to add suspension help (extra spring or air bags).
