To find the GAWR for a *specific* Ford E-350 box truck, you need to:
* Check the vehicle's sticker: Look for a sticker on the driver's side doorjamb or elsewhere inside the vehicle. This sticker will list the GVWR (Gross Vehicle Weight Rating) and the GAWR for the front and rear axles.
* Consult the owner's manual: The owner's manual will also specify the GVWR and GAWR.
* Check the Ford website: You might be able to find specifications for different E-350 models, but you'll need to know the year and specific build details.
Without this information, any number I provide would be a guess and potentially inaccurate and unsafe.
