200 is about all I want to drive. However, in answer to the original thread, I would probably split the 625 miles in half just to save another night in a motel. I would probably not do this unless I could drive on the interstate at 55-60. My O/D makes that very doable. Even so, prefer to just drive 200 miles a day. My old body tires out much quicker than it did 40 years ago, lol.
