John, You are correct. Bob did my "Train the Trainer" class back in the day. Great guy! I am with Thompson....out of our Tuscaloosa Branch (God's Country) Roll Tide! I've been told recently that the operator presence system will be like the seatbelts. For all lifts manufactured after a certain date, they'll have to have it on them. Anything older will be grandfathered in. After all of these years, I'm very familiar with what OSHA requires and where liabilities lye.
