To find the exact weight of a *specific* F-250 Crew Cab Diesel, you would need to:
* Check the Ford website: Go to the Ford website and use their build and price tool for the specific year you're interested in. The final specs will include the weight.
* Look up the GVWR and curb weight: The Gross Vehicle Weight Rating (GVWR) and curb weight (weight of the vehicle as it sits, no cargo or passengers) are often available in owner's manuals or online specifications for specific years and models. The curb weight will be the closest to what you're looking for.
* Check the vehicle's sticker: The sticker on the driver's side doorjamb usually lists the vehicle's weight information. This is the best source for the specific vehicle.
Without knowing the specific year and configuration, I cannot give you a precise weight. Expect it to be several tons (over 6000 pounds).
