You won't find one single answer. To find the weight of a *specific* Silverado 1500 LT, you need to:
* Check the vehicle's sticker: The sticker on the driver's side doorjamb will list the curb weight for that particular truck.
* Use the Chevrolet website: Go to the Chevrolet website's build-and-price tool for the Silverado 1500. Input the specific options for the LT trim you're interested in, and the website will provide the curb weight.
* Consult a resource like Edmunds or Kelley Blue Book: These websites often have specifications for various vehicle trims and years.
Expect the weight to be in the range of 4000 to 5000 pounds (1814 to 2268 kg), but this is a broad estimate.
