Need measurements for floorplan

[Dixie Bushcraft]

I figure someone has the answer to my design problem.

Actual inside measurements should be easy to find with all the conversions going on, and done. But I see no posting of what people got when they pulled a tape.

I would like to know the actual measurement from "behind the line" to rear door on a front engine CABOVER Bluebird AA 14 window 40'.
And the (stock) width.

Also, for a 13 window International or Freightshaker CONVENTIONAL bus from the "line" to rear door.
(just in case we can't find a cabover)

If I can get a better (within a few inches) idea of what I can expect to have to work with, I can make a better decision about which type I want to buy.

I like CABOVER. (no hood)
CONVENTIONAL (proper name for having a hood) is okay too for ease of maint.
But both have upside and downside, so I am down to floor space and ease of deign/build. And for that I need measurements.

Thanks in advance.
