I guess what I'm getting at is it seems as if many refer to the "light duty transmission" in the eco as the concern with towing over what's recommended by the factory. It just seems odd if the tranny behind the hemi and eco is the same and the hemi properly equipped can go into the mid 10k range why it would be a problem with the eco. Don't get me wrong, if I had something that heavy and was towing frequently then in my opinion there would be nothing less that a 3/4 ton in my shop.
