[stockley1234 0]

Width: 38" left to right (between wells)

Length: 33" back to front

Height: 18" top to floor

Opening:

The 17" is the trunk opening, as if you took a tape and measured from the top of the trunk (weather stripping) to the weather stripping by the rear bumper. The vertical 12" is from the top of the trunk (weather stripping) to where it intersects the horizontal 12" is from the trunk opening from the bumper. I think from the weather stripping to the floor was 20"
