* Specific Engine: While it's a Cummins, there were different versions (e.g., horsepower and torque ratings) available in 2006. A higher-output engine will have a higher towing capacity.
* Axle Ratio: Higher axle ratios allow for greater pulling power.
* Payload Package: Options and packages added to the truck will influence the amount of weight it can safely tow. Heavier options reduce the towing capacity.
* GVWR (Gross Vehicle Weight Rating): This is the maximum weight of the truck itself, including passengers, cargo, and any added equipment. Exceeding this is unsafe and illegal.
* GCWR (Gross Combined Weight Rating): This is the maximum weight of the truck *plus* the weight of the trailer it is towing.
Therefore, there's no single answer. To find the exact towing capacity for *your specific* 2006 Dodge Ram 2500, you need to:
1. Check the sticker: Look for the sticker on the driver's side doorjamb. It will list the GVWR, and likely the towing capacity for your specific configuration.
2. Consult the owner's manual: Your owner's manual will provide the most accurate and detailed information about towing capacities for your truck's specifications.
Keep in mind that the advertised towing capacity is a maximum. It's always best to tow below the maximum capacity to account for variations in road conditions, terrain, and cargo weight.
