No kidding? That's a bummer about using a crawler motor and how it doesn't tie in properly with the engine sounds. I was planning on a 55t motor (if not slower) for mine. Now I may need to reconsider.
There's several features I'd be happy to give up with an MFC. For example, I don't need to remotely operate the lights. I'd be happy to flip a switch on the truck. I also don't care too much about having a horn. I think I'd be happy just being able to start/stop the truck remotely and to be able to shift the transmission. Not sure if there's any other MFC functions I'd really miss all that much. I really just want the sound and vibration.
Can the functions of the MFC be activated via the control box within the side steps, like operating all the lights?
