Unfortunately, most of the rear mounted stands I've tried tend to rattle a bit. The center of gravity is located at or near the rear axle and the springs in these products don't seem to be strong enough to hold them closed when going over rough terrain.
Although I much prefer a center mount kickstand, my bike is rear heavy and tends to tip because the stand is too far forward. I tried a variety of rear or chainstay mounted products and the one I liked best was this one from Bontrager:

You need to verify the bolt pattern though to make sure it will fit your R&M. There are dozens of similar products out there. Perhaps someone else can recommend something specifically for the R&M.
After some modification, I eventually went back to the center mounted stand.
