To find the height, I recommend checking:
* The Ford website: Look up the specific year and model of the E350 on the Ford website. The specifications will be listed there.
* A vehicle specifications website: Sites like Edmunds or Kelley Blue Book often have detailed specifications for various vehicles.
* Your vehicle's owner's manual: If you own an E350, the manual will state the exact height.
Without more information, I cannot give you a definitive answer.
