New C on Ford chasis. 5 or 6 speed?

I just picked up a new 2019 Forest River Sunseeker 2290 on the Ford 450 chasis with V10.
I’m not sure what transmission they’re using. On the indicator it has D 4 2 1.
I’m pretty sure it’s the Torqueshift but not sure if it’s a 5 or 6 speed?
The power and shifting is great.
