Ironically, I also think the TRX was the "better" buy for most drivers—even though it and the RHO should perform almost identically off-road, the TRX was significantly faster. I assume that most owners use their trucks on-road the majority of the time, so I consider that edge to be significant. At least with the way I drive, I'd much rather have a faster truck than a more off-road capable truck.
Both are blisteringly fast, but the TRX was approaching sports car speeds (3.7 0-60) while the RHO is much less impressive at 4.6...
