hitch with "off" and "on" to control as bars

[dlenloe]

Do you run with the switch to "off" meaning the are bars unlocked? When we bought our AS 23FB we were told to leave the lock "on" and only unlock when backing if needed. We started having issues with the ad bars causing the saddle clamps to move. Well, $162 later we are now being told that we run with the bars unlocked meaning the "off" position is engaged. The hitch is the Recurve 6.

Well, since my phone wants to auto correct everything it doesn't like, let me clarify some of the weirdness in my question. When the mention of "as" bars shows up, it should be "WD" bars just as "ad" bars should be "WD" bars as well.
