Cable support on slide outs of 3400RL

[ChiefKB]

Has anyone had a problem with the plastic cable supports on the slide outs that get folded with the slide goes in and out. It's a pice of plastic about 4" wide that has loops that hold all the cables together. Recently I had this support on the deck slide out break at the outermost connection to the slide out. I just checked the living room side out and it is cracked in the same place the other one broke. Of course, it 2 months out of warranty and Keystone says too bad, so sad! I checked the third slide out (kitchen) and found no crack, but you've got to wonder if 2 of the four have or nearly broken....
