The Dana Dolly is a great way to add dynamic movement to any shot. It's portable, quick to set up and is easily adjustable supported by 2 low boy combos. Lay it on two apple boxes for a low mode shot or on any flat surface. Under sling the camera for more shooting options. We've also attached the slider on top of my Sr. Magliner cart as seen below, for run and gun stable dolly like shots on the fly. Available with track from 4ft up to 10 ft.
