You won't find a single definitive answer. To find the weight of a *specific* 1997 Dodge 3500, you'd need to look at the vehicle's sticker (usually located on the driver's side doorjamb) or consult a 1997 Dodge 3500 brochure or owner's manual for the specific model. The GVWR will be listed, and the actual weight will be somewhat less than that.
