I honestly have no clue, but on my Interstate it's inside the same cover as the dashboard fuse box, not in the open. Yours might be similarly hidden.
Of course, any RV that uses custom coachwork on a bus chassis might
have the OBDII port in the engine compartment, because when the engine/chassis was delivered to Airstream there was no dashboard to even mount it to.
