Mine (2014 Hurricane 32A) can turn to face rearward enough to blow on driver/passenger... but...
If driving - more than once I have had to turn them on blasting the windshield to stop fogging - wouldn't want to have to reach up and turn them back to be able to do so... I use the dash vents for me and leave the fans facing forward for safety.
Now I have considered hooking up alternate power to fans (through heavy duty diode like that used in toad taillight wiring isolation) so I can run them off the house batteries when parked. Normal power requires ignition on.
Hasn't bubbled to the top of the list yet to do.
I have added similar 12v fans in the kitchen area and bedroom for air circulate when boondocking running off the house batteries.
And as mentioned - have to be sure if turning them - that they clear the overhead bunk lowering. The overhead bunk wins that battle.
