I remember working on an older Towmotor which , by the model number, led you to believe it was a 3000lb capacity truck. The capacity plate also rated the truck at 3000lbs- but at a 16" load center. I believe it was a marketing ploy to make a 3000lb truck look really small ( the trucks size was extremely small for a 3000lb capacity). It taught me to always inspect the data plate when checking a unit's capacity.
