For the most part it shouldn't be to much different. It's best to shoot me an email or a PM before you do any repair so myself or one of our engineers can walk you through it.
Will the existing threads about repair and maintenance of a RD still be of any use for RD2? Or will this be a "let's start from scratch"-kind of thing?
I'm thinking that with the additional foam and the different silicone things might be different.
