Probably not needed on a 2500. What is the trailer GVWR and what "weight carrying" rating is given for the hitch receiver? I doubt if the tongue weight on your trailer exceeds 1200 lbs and that should be well within a 2500's payload and hitch receiver capacity. Every 2500 configuration I see has more than 3000 lbs of cargo carrying capacity, so as long as the receiver itself can handle the tongue weight, it should be fine. The 2500 should be equipped with a 2.5" receiver and those are typically rated for more than 2000 lb of weight carrying. Some brands run 2700+ lbs.
