We promised to pass along as much of the towing specifications we could get from Ram, and here it is.
For the sake of simplicity, we've compiled as many of the configurations we could get onto a single chart file. As you might imagine, there are a lot of 2500 and 3500 configurations, so the file has 21 different charts sorted by weight class, powertrain, trim level and cab configuration, as well as (long and short) RamBox usage.
The maximum fifth-wheel towing and gross combined weight rating numbers for the 3500 HD dually can be ordered in several trim packages, but require, as you might expect, 4.10:1 gears, the Cummins HO and an automatic transmission. It will carry a 14,000 gross vehicle weight rating. The highest payload number on one-ton models is 6,730 pounds; the lowest is 3,390. The lowest GVWR for the Ram HD 3500 is 10,000 pounds. Of special note, gearing choices for both standard 2500 and 3500 trucks include 3.42:1, 3.73:1 and 4.10:1 gearsets. The Power Wagon remains at 4.56:1.
Three-quarter-ton models will have a good range of ratings, with their lowest GVW/payload numbers at 8,800/1,700 pounds, with the highest GVW/payload ratings listed at 10,000/3,170 pounds. We should note that the Power Wagon and 2500 CNG have slightly lower numbers because of their unique setups.
2013 Ram HDs will continue in a variety of trim levels: ST, SLT, Tradesman, Bighorn, Lonestar, LongHorn, Outdoorsman, Laramie and Power Wagon.
We still don't have all the specs on the larger commercial-duty 4500 and 5500 trucks or pricing; we expect that at a later date.
