Hi Otis, Are these sileage clamp sides? How long how wide? If there 3-4 ft wide but 8-10ft long you could.....
Try an L shape with two at different heights giving you three heights including ground level?
Try two together lengthways like a pyramid shape (you could lay one side of your L on top of one end), this would be a nice knife edge to get over?
One could be made up as a steeper than 45 degree lengthways ramp up the back of an earth mound, on the opposite downward side stand one vertical but led horizontally as a low splatter wall to hop up onto the mound from ground level?
The last you could lay horizontally but at 30-40 degrees as a killer side slope?
