Cool! I've got the pic of my 2002 Superduty at 200k miles about 2 miles up the grade towards Wyoming from the I-80/I-84 split in northeastern Utah, in January 2012, at 2:25 am, temp showing 5 below zero, headed east for NC. Engine never shut off from Park City, Utah to Raleigh, NC (tag team driving with my son and we had to leave her idling while fueling and catnapping because it stayed brutally cold all the way home). She's got 287,000 now and will be pushing 295,000 by the time we get back from Montana in August. Your Big Girl has served you well, hasn't she?
