So I've been getting a gap about 2 inches at the bottom of the slider after it sits retracted for a couple days. This has been happening about a year or so. Now this last trip when packing up, it wiggles back and forth while retracting. Stepping on the floor part of the slider had a bounce it never had before once it was ready to travel. It is hydraulic with electronic control.
Is there any maintenance like grease points I should be aware of? Is there a way to adjust to tighten the gap when closed?
