The slides are independent. It is the kitchen slide that I am most concerned with.
The living room slide is much wider and does not have any weight at the top, so it is naturally more stable. Also, I could put multiple support bars on the living room slide if need be.
The kitchen slide however, is only 23 inches deep and has significant weight at the top: microwave, food cabinet, refrigerator, TV/Entertainment center and fireplace. Also, when the kitchen slide is in the travel position you no longer have access to the rear of the camper, so you could not place a support bar anywhere except at the front of the slide.
I have a request into GD support for action, and will keep the forum advised.
