Looking at these numbers and forums for towing and it is very annoying. Most of these trailers say micro or light but have 900 to 1,000 lb tongue weights. Basically, you need a 2500 to tow anything but a pop-up camper.
Some half tons have payload ratings higher then some 2500 series trucks. The point is - the badge on the side means nothing, you need to match the truck to the trailer using the stickers on the door.
