The differences are:
#1 The main fabrics are still 20D polyester but they’re not made in Japan. It's now lighter and even a little stronger.
#2 The side windows are changed from 3 round windows per side (where only the little ones closed) to 2 larger half-circle windows per side that all can be zipped closed. Following that change, there are now two clear windows in each side of the rainfly to match the tent.
#3 The vestibules of the RugRats were different on the two sides: one was a 1-point vestibule and the other was a 2-point. On the MoonLights both are identical 1-point vestibules.
#4 Almost forgot: It's a small thing but kinda cool: the rainfly can now be easily pitched with just the poles - no extra hardware needed.
