I use a telescoping ladder rather than the factory ladder, the angle makes it much easier to climb. I generally wrap an old beach towel around the top of the ladder before use, I feel the padding prevents scratches and spreads out the pressure on the fiberglass a little more. I've used it all around the coach with the exception of awning area like you mentioned, no problems. When on the front end I try not to let the ladder lean on the glass, no particular reason, just me.
