Interesting to see what folks feel catches the eye and what does not. As a new RVer, awnings in their shells do not really say 'RV' to me. They are similar to the long pieces of 6" PVC that plumbers (and others) use to haul materials on the roof, for example.
It's funny how people keep thinking I mean stealth when I don't :). Maybe I am not articulating very well? It's just that I notice a Roadtrek (with the decals and all) from two blocks away, in a city. It sticks out. I don't like to be so noticeable -- not because I am hiding, I just don't like the attention. Same reason I dress plainly and don't holler a lot in public.
An obvious RV also seems like a target for breakins, even parked in front of my S&B.
For me it's color that sticks out. If everything -- awning shell, AC, roof vent, etc. -- is the same color as the body, and there is not more writing (name brands, etc.) or striping than regular cars, then it blends in. Although the dropped floor is also pretty eye-catching...
