Well over the weekend I passed by a local trailer manufacturer in Columbus Ohio that had the biggest commercial trailer I've ever seen hooked to a 2nd Gen 3500. It was not an overly long normal construction gooseneck type trailer. It was 57 feet long with no floor deck and the axles were spaced about 12 feet apart. I called them today to ask what it was and the salesman said that they made it for themselves to use. They use it to transport straight boxes for delevery trucks like HH Greg or Best Buy uses. It can handle two 24 foot boxes on it. The driver is out picking up a load and will be back later this week. I will try and get a picture of it and post it when it comes in. What's the longest or biggest load you've seen hauled by a Dodge pick-up?
