I have a Marksman and they are in Santa Fe Springs. He makes them for United, Penske, and many utility companies. I have a 14k gvw thats is down graded to 9980 so you can legally tow it empty. Whatever you do don't get a triple axle if your running over 10k rated unless you have a commercial DL. You will get popped at some point. Ask me how I know.
