I just bought a 2011 Roo 21SS. There is a hole in the center of the curb side fender flare. When you look in through the hole, you see a fitting on the frame into which the speed wrench the dealer said was for the slide would fit. I haven't tried using it, so can't comment on whether there's any truth to there being an electric brake. Fortunately (knock on wood!!!), I've had no trouble with the slide....but then, I've only used the trailer once so far over a weekend -- I've had the slide in and out probably less than a dozen times....
