The other thing I didn't mention is I keep two 4'x2' storage bins in the back of my site to keep items stored that I'm not using for a particular trip (instead of dragging around weight). I had these on my last smaller spot (at the same storage lot) for the last 3 years and never had an issue. They are well inside my allotted site. These storage bins had been "pushed" back about a foot into the site behind me. The neighbors power cord runs right in front of these storage bins across my site. I think that bothers me more than the slides being extended. Of course I don't know who moved them but I would never touch anyone's property.
