Exterior Door Stop Ideas?

There is a post on Forest River Forums in either the Sunseeker or Forester sections, but I can't seem to find it at the moment; they took a handicapped handrail & cut it off, then added a rubber cane tip on the cut end. They mounted it on the wall below the awning, and removed the gas shock. I'd like to do something similar, but I haven't taken the time to think it through.
The shock mounts on the threshold & bottom of the door are weak; they were not designed for a shock. Ours was sloppy on the day we picked it up, but it has held together.
