In the January "Towing Guide" issue of Trailer Life, they showed that both the 2005 Ford Powerstroke 2500 and the 2005 Chevy Duramax 2500 have towing capacities of nearly 3000# and a GCWR of 3000 # MORE than the Dodge Cummins 2500, given all things equal, i. e. automatic transmission, 4. 10 rear ends and SRW, 2 X 4, etc. At the one ton (3500) models, all 3 trucks were rated to have the same capacity at 16,500 towing rating and 23,000# GVWR. I doubled checked the websites for all 3 trucks manufacturers and that is exactly what Dodge, Ford and Chevy show in their own literature. Why would Dodge's 2500 truck have a lower rating than Chevy or Ford's? By the way, Ford and Chevy give this rating for 5th wheel trailers, Dodge does not make any differenciation. Secondly, I noticed in Dodge's Truck website, they show that the Cummins is available only in a 4 speed automatic but nothing available in a 5 or 6 speed automatic. Is that true? I thought the H. O. version came in a 4,5, or 6 spd. auto.
