I own a bread route and am looking at this 1500 with the 3.0 diesel. Short bed. Was told needed a 2500 but saw on ram chart it can pull 9,300. Is that accurate? I would need a 20 or probably 25 ft trailer, big days in my box truck i have 22 to 23 stacks, lots are 17 high, each tray weighing from 7 to 15 pounds. Thanks!
