In the past I've used the Landing Pads - it's a great system where you can easily remove the bar/tower assembly leaving behind only a streamlined and barely noticeable pad.? Our newish-to-us 2001 has, I assume, some ducts etc. in the ceiling (heat/AC) such that I'm hesitant to start drilling away w/out some clear knowledge of where it's ok to mount the pads.
Has anyone done this and/or can anyone point me to diagram, dimension, photos or anything else that would show what locations to avoid?
thx
