The client has a 400-acre ranch. She hauls cattle to and from auction. Where can I place the stock trailers, hay trailers, and dump trailers she has? Also, she has horse trailers (as she rodeos as well). I am told I can put the horse trailers with progressive under travel trailers? Does anyone have any insight? Missouri. TIA
