humble1, I'll snap some pics this weekend, maybe even a few with the boom and shrub wand in action. A 50 or 200 gallon skid is not practical for me. As I said, too many obstacles between lawns and road. Also, what you can use on zoysia and bermuda must not go anywhere near st augustine. What is sprayed on centipede is lethal to all other turf grass. I like the ability to wash out the sprayer on the previosly sprayed lawn and go on to the next one. The DOA has the sense to allow that. Could not imagine the large amount of hazardous waste generated if I had to store all of the tank rinsings instead of spraying it out on a labeled site.
