Cummins,

No, I've not used a lock washer. I actually got this idea from someone here on 5th Wheel Forums or over on SOITC's site. I can't remember who or where for sure.

As for needing a lock washer, unless there is enough vibration from the a/c running or traveling (whenever we finally get to do that), I might have to add some lock washers.
