I'm not sure how much difference "additional off-road capability" matters on a vehicle half a block long. In the case of the Raptor (150 platform), the softer long-travel suspension makes it a less-capable towing platform but I'm not sure how much of that higher-speed-off-road tuning went into the Tremor and how much of it is bling.
