I use the Lance centering guides, ordered them from the factory.
However, they do or rather have rubbed against the camper when it shifts slightly, so the padding added onto yours may be what I need for mine.
Jefe4X4 mentioned in another post using the Lance guides too, but his solution was putting some sort of angled metal along the bottom of his camper to protect it.
I have a small strip of angle iron on mine to protect the plywood and to give a slicker surface to slide down into the guide.
