I did the same as viperdave did on my 2016 1500. I don't know what the 2500 is actually rated at but my 1500 is actually rated at over 3/4 ton. I know the suspension is roughly the same between the 1500 and 2500 except for heavier coil springs on the 2500. But, I have seen new 2500s with less trailers than I pull and they sit about the same as mine before I added the bags. I only run 25 lbs. and it makes a big difference.
