My slide came with a topper, so that isn't an issue for me, however for other reasons, I purchased one of those folding ladders that folds into a small enough square that it stores inside the hollow bumper. Folks report that that's a bad location for storing a stinky slinky, as it rusts and gets rough in the tube, so it wears through the slinky.
Having a sturdy folding ladder in camp is a very handy tool.
