* Engine: The 5.7L Hemi, 6.7L Cummins Turbo Diesel, and the 8.0L V10 all had different towing capacities. The Cummins diesel offered the highest.
* Cab Configuration: Regular cab, extended cab, and crew cab trucks all have slightly different capacities due to weight differences.
* Drivetrain: 4x2 (2WD) trucks generally have a higher towing capacity than 4x4 trucks (because of added weight).
* Axle Ratio: Higher axle ratios generally allow for greater towing capacity.
* Specific options and equipment: Added weight from options like heavy-duty towing packages can affect the capacity.
Therefore, there's no single answer. To find the exact towing capacity for *your* specific 2006 Dodge Ram 3500, you need to check the sticker located on the driver's side doorjamb, or consult your owner's manual. The information should be clearly stated there.
