I am thinking about replacing the foot pads on the front legs of our 5th wheel. Currently we have the standard rectangle ones, and I am debating on purchasing the 9 inch round ones from lippert that fit the square legs. Does anyone have real world experience with this swap? Have you noticed any difference with the bigger round pads? I also have JT strongarms installed as well just not sure if changing to the round foot pads makes that much sense.
