It sounded like you were stating that there were other three character codes than YE9 that mean a truck is a Cheyenne Super.
Edit - btw, Keith wrote up a great explanation of what those extraneous characters can sometimes mean. Worth a look, I found it very interesting.

Just my ignorance of RPO characters on display Jocko. Learn something new everyday.
I can't quite reach the write-up, but I see "
The additional characters are either ECL codes, which provide additional detail about the RPO, or dummy characters filling the spaces after the added codes fell into disuse." And "
ECL Exception Control Letter".
That alone explains a lot.
