So I just got my update from the dealer. Jayco is sending the parts to reinforce the supports, but will not upgrade the slide motors to the 500:1. Jayco says "this will throw off the timing of the system." So instead they are replacing the motors with the same 300:1 motors. Not sure that I buy there fix, but I'll let them replace and time will tell if I need to bring it back and insist that they do the repair with the stronger motors. Now I just have to wait for the parts to come in.
