The WK vehicle mount is very well made and great for versatility since it has both a Mitchell mount and speed rail mount option.
As far as a harness and safety gear, I use this full-body climbing harness, and typically wear it backwards so I can be clipped in on my back. I also have this climbing harness, though I have never used it on a job since I always feel safer in the full-body version; I want my full torso secured rather than my bottom half only. I'm usually clipped in via thick webbing and and a strong carabiner clip meant for climbing. I carry several length loops and thicknesses of webbing in my kit, and lots of carabiners.
I also wear hard side skateboarding knee pads and a helmet (I use one from horseback riding, since the potential fall height and general speed is about the same - if we're going faster than a horse, I probably don't want to be doing that shot!). In addition to protection from falls, knee pads and helmets are also useful if your knees/head are near speed rail, knobs, or any other hard object that you could whack into while in motion.
Make sure you have something soft to wrap around a pole if you're leaning against it (like an India mount or speed rail), and a place for your feet. I carry a spool of thick webbing (easy to find at REI or marine supply store) that can be cut and tied off to use as stirrups in a pinch.
It's also good to have some vectran (check a marine supply store) for a very strong but thin rope to tie off the arm to keep it from bottoming out or extending past its intended reach - also useful to keep it secure before the sled goes on.
Finally, make sure you have a method of clear communication between you and the driver so you can communicate immediately if you need to stop in an emergency.
Happy (and safe) flying!
