inspection of island has led me to conclude , a poor fastening design by Forest River. The toe kick is the only spot that small 1"x1" blocks are used to hold the island in place. When the slide closes, the "L shape island " is relying on those 1"x1" blocks to support all the weight. Over time the toe kick gets weak, and starts to separate. By adding a support on the outside end of the island thru the access door on the outside of the rig,I was able to add the much needed support.
