I have been known to wash the dirt and mud the dash, seat and floor in my cabbed tractor with a hose on occasions as needed . Been doing it for 5 years or so with no apparent downsides. I don't "flood" the dash (I wouldn't on an open tractor either), but ain't particularly cheap with the water on the floor, interior side panels or seat. I have never washed the roof where the speakers and AC outlets are (it has never needed it), and stay away from the gps, back up camera, phone charger connection and utility outlet, all of which I have added. As near as I can tell, with those few exceptions, all the driver's area components are similar if not identical to an open tractor. I have never noticed other brands to utilize different cab specific equipment either. I wouldn't be overly concerned or treat the tractor differently if a door or window were missing, but I would replace it soon just for my comforts sake.
