I set up the DL 1608 on a milk crate next to a speaker stand, on the floor. The DL is off the floor to stop crap getting in to it and to allow air flow around the mixer. I would set an X18R up the same way. Never directly on the floor. You're just asking for troubles. I agree that you would need some sort of road case to carry it in, to prevent it from getting beat up in transport.
