I was purchasing a new Jayco Entegra Condor at a RV show, being sold by La Mesa RV. When I looked underneath, the nylock nut was missing from the passenger side, rear anti-sway bar. I brought it to the attention of the salesman, and the following day, it was replaced with a standard fender washer, lock washer, and nut. The RV, at the time, was new and had less than 1,700 miles on it. Had the bolt fallen out, the one side of the anti-sway bar would have become unsecured from the vehicle, possible causing stability issues while driving. I’ve attached a photo of both the left and right anti-sway bar attachment points with the current bolts, washers, and nuts.
