Hmmm... I can't picture how the breakaway cable can move and get snagged like that IF
the Revolution is properly activated. On my Rockwood with the Revolution activated, the breakaway switch, which is screwed to the side of the pinbox, does not move with respect to the hitch or bed because the pinbox does not move. Thus the cable does not move - it just lays there hanging between the switch and the slot on the left end of the back rail where I clip it. Have they moved the breakaway switch up to the camper body so it moves?
About the kitchen slide cable arm... yes, mine broke at the outside end too. Probably a lot of people have broken ones and don't know it unless they get curious about the low-hanging cable bundles. The way its attached is problematic because they just drive a few screws through it into the square post at the slideout side end. Then, there's too much stress on the plastic due to the flexing at that point and the heavy load it carries. I just told my service manager about it, sent pictures and he ordered me a new one (free under the second-year warranty). In the meantime, I fixed the original by trimming it square and using a stainless steel piano hinge to attach to the post so there is now no bending stress (just the stress of the weight of the cables but its well distributed via clamping with multiple bolts and washers). I replaced all the cable hangers at the same time because about half of them were broken due to the heavy load and cheap design (the few they sent with the replacement arm were the same type and useless because you'd have to disconnect the lines to use them). You may have to do the same eventually and here's that thread
