I would try installing them behind the bottom aluminum skirting. I would think you could Gorilla tape or silicone and adhere it to the coroplast. Of cousre you would have to climb under the rv to do this but you won't have to worry about damaged the outside.

Not sure what you plan to do with your slides but this approach might work really well for you if you work the slides. Maybe add insulation to the coroplast on the slide from below if the slides are out all the time.
