I need my camera to slide very close to the ground. I would like to mount the slider upside down. Bought the small leveling legs for my kessler pocket dolly but they are just not high enough. Any good idears how to mount the slider so it can hang upside down from 35-60cm. It shall be possible to level the legs because the ground will not be completely flat - more like dunes, heath and grassland.

Support the ends with apple boxes if the legs aren't long enough. You could also consider mounting the camera on something like an articulating arm. Apple boxes or even small blocks of wood under the inverted all-terrain feet seems like the easiest solution though.
