I installed a power wheelchair and carrier in the cradle of my 1999 Chevy Tahoe. The only problem was that if there was a dip in the street (IE crossed another street and went through the gutter) the carrier would get scratched. While it wasn't enough to cause damage, it wasn't good. This was installed to fix the problem and did exactly what I wanted. There are no more scratches, but the ride is still good.
