I am in the process of helping my father inlaw purchase an 04 3500 Ram. I have an 01. 5 and was wondering what problems that I know about in the 01s carried over to the third generation trucks. Do I have to worry about fuel pumps? What about the improved auto transmission? I have an edge box and a DTT valvebody upgrade in mine but I never drive in OD below 1500 rpm and about 1700 rpm when pulling 8500lbs. Will he have the same concens? I know he will not want to upgrade the trans and he puills a 12000 fifth wheel trailer. Nay info you guys could pass along would be appreciated.
