The mounting is very good compared to the Rigid Industry ones. The 22" has 4 feet with rubber pads on the bottom that are height adjustable. You can barely notice them and the bar sits less then 10mm off the surface the feet are bolted down too. The only way to remove the light bar is to undo the 4 nuts, if they are hard to get access too then your on a winner because people can't steal it.
This should give you some idea, if you want a better picture let me know and i'll get one for you today (ignore the rubber chocks under the front, they were temporary while i tested the angle i wanted it at).
