Very stable. There was a modification on the MLVW to install separate controls for the left and right wiper, and to vent the expelled air from the wiper to outside the cab. The reason for the venting was so the cab wouldn't have the smell of musty compressed air whilst operating the wipers. Not sure what MLVW Ottawa drives, but I can assure you that anything out this way had plenty of venting in the cabs with no extra modifications.
