We bought our 2000 Coleman Sea Pine early this summer. The folks that had it before us seemed to have taken very good care of it, keeping it in a garage when. It in sue for annual family beach trip and a couple other trips in the year. They cleaned and maintained it well from what they said. We popped it up in the driveway a couple times and then on our first weekend trip popped it up and heard a snap. One lift cable down. Our co-owners used it for two trips. They take better care of things than we do, put new tires on, checked everything over and still used the board for elevating the side that had a broken cable. Nothing else happened. Then, this weekend we took it out again and again, during lift heard even louder SNAP! All of the remaining cables broke. A campground host and some other folks said it happens a lot on pop-ups but this seems crazy. Are we doing something wrong for it to happen to us like this? We have to somehow get it repaired now but I'm worried if we do find the money to get it repaired whatever we've done wrong will happen again. Please tell me if this is normal or if you have any ideas what could have gone wrong?
