So my family and I were out in the middle of Alaska, no cell reception kind of place, and when bringing in the main slide out of our 31BHPR we heard a loud thump and the slide out stopped in its tracks. I went outside and saw one of the lower cables had a bunch of slack on it. I went back inside and looked above the slide and saw that the In and Out cable connections had locked up on each other and snapped one bolt on the In connector and bent another one. Luckily I was able to reach up there with vice grips, pliers, socket, etc. and was able to get it back enough to get the slide back into place. I did notice that on the other set of In and Out cables, that things were getting loose and I will have to tighten up the nuts.
Hope this hasn't happened to anyone else. You may want to take a look at those cables when your slide out's are in the 'in' position and make sure they haven't twisted themselves together. The design has these In and Out cable connectors bypassing each other when the slides go in and out and it looks like they have the ability to hook up on each other.
