I use an SV Technologies mount for my stills and an IO Port for mounting my small video camera (Canon Elura 100).
If I'm using both cameras I mount the SV facing forward on the roll bar and shooting over my shoulder and the IO Port on the passenger side of the roll bar.
The SV is very stable but, since my roll bar is angled slightly back in my ERA, it's difficult to get a good alignment with it swung out to the side. I have, however, used the SV successfully with my large Panasonic video camera (DVC-30). Just took some creative adjustments.
