That was just a semi-educated assumption (?) due to the added weight & torque of the diesels over the gas powered units that there must be additional bracing or gussets stock. I would also assume that any 1600 that had a diesel as an option would have had those added on w/ the engine. But that is just my pure speculation . . .In what way are the frames stronger than a 1600? The reason I ask is my 1600 has a Cummins and an Alison so I'd like to compare.
Hey David, where do you put the 4500 series?
