I have a 2013, Bighorn 3010RE. The bottom cables on the bedroom have about an inch of play( when I pull down or push up on them) when the slides are fully out. The top cables are very tight. Can anyone advise me as to whether this the proper tension or not. I checked with friends of ours who have a Landmark and it was similar in tension as ours. The slide works great so I am thinking this is normal
