Welcome aboard. I am one of the lucky ones wherein the seats suit me just fine. I have done 375 miles in a day, and 426 miles in two days, with no discomfort. (I realize that many are not so comfortable.) I have single-charge legs of 242, 226 (2), 218, 200 (4), and 175 (2) miles. I have driven 7555 miles now and have "rotated tires" once.
