I don't have the RRO but this is what I know. I have had no aligment problems, no uneven tire wear. You will not have as much downward travel in the front (there are a few ways to fix that cheaply) and should put a longer shock in the back. If you are not doing anything really crazy then it will be ok until you can upgrade. I have 2inch spacer on the front and am waiting for the rear. Roadless gear has the 2inch vrs the 1 3/8 spacer from RRO.
