There are a couple of reasons that my mount won't work for an RT. 1) you would have to cut something. 2) there is very little chance that a camcorder would fit in the space available under the sport bar. 3) back glass removal/installation is a challenge. 4) having a mount that sets the camera forward from the GTS position would make it likely to be struck by an occupant's head in a crash.
I've thought about it quite a bit and the risk/botheration factor exceeds the potential rewards.
