I was out with Brad Tucker last summer shooting at Dinosaur Provincial Park. We were getting some driving footage. I had tried to use other vehicle mount rigs but the results were usually pretty poor plagued by too much vibration. FilmTools 3025 kit is by far the best kit with almost no vibration. When we went on the gravel back road in the preserve at Dinosaur Provincial Park Alberta, Brad decided to gun it which increased vibration. I had couldn't believe the shoots on the gravel road were actually usable. I believe the using the wide angle Tokina 11-16mm f2.8 was key in reducing percieved vibration. If you know you're going to be shooting on a rough road try to shoot as wide as possible. We also had Go Pro cameras mounted but the vibration was horrible in most of the footage.
The FilmTools 3025 kit performed incredibly well as you can see from the video even on the rough road.
