Our 2019 Elite 2 only has the Cube Side Manual Awning, we bought it used, so we didn't have a choice, glad it is a manual awning. However, if we did have a choice, I think we would order only the Cube Side.
IMHO, the Cube Side Awning is as large/popular as it is on most RV's, principally because of it location/usage, i.e. Entry Door, Eating Area out doors etc. On the other hand the Road Side Awning doesn't need to satisfy these areas, although they could have limited beneficial on sunny days. Most RV's, Trailer or Motor Homes use Single Window Awnings to block the Sun/Rain. The Single Window Awning design has the benefit of not being as vulnerable to High Winds, I think they look better also! Additionally, the Single Window Awning has the added benefit of blocking the Sun/Rain from entering the Back/Front Windows, if so equipped.
Hopefully, one day our Oliver will have Single Window Awning (Dark Blue) on the Street Side and the Back Window. I was researching these again just this week! As I mentioned earlier, we really like the Stylish Look of these as well as their functionality!
