Mine I just have a metal plate similar to OC's with holes drilled at each corner. An old broom handle screws into the bottom with a sharpened end. I just shtickit in the ground wherever I need then use the holes in the plate for tie downs. Compact, very light weight, and versatile.
I like your stand but am fearful of the wind. I had a dish on a tripod at Moab, Utah when a sudden gust of wind slammed it to the ground and broke something. It never worked again. That is when we bought the Tailgater. I have been afraid to set it on anything that it might blow off or blow over. As soon as my warranty runs out I plan to tap the bottom of the tailgater and attach a metal plate to it (Thanks to Old Coot for the idea). I already have brakets made that will allow me to attach it to any of the four corners of my toyhauler.
Be sure to anchor your stand firmly to the ground. My tripod that blew over had a gallon jug filled with rock.
