I got back from a run on the day before Thanksgiving and as I was closing out my log book I noticed I had gone over 600,000 miles, 600,514 to be exact. I didn't know if I was going to keep doing this long enough to make 600,000 but the truck is still going and things have slowed down enough that I'm able to keep doing it. My wife says this is a good retirement job. Just put 4 new Michelins on the back of it today so I guess I'll need to run a while longer. The only real problems I've had with the truck is the rear end. A 4500 would have been better but they weren't available when I got this one. It was one of the first ones out, build date 10-06. If I can remember how, and can make them small enough, I'll post some pictures of the truck under load and the odometers. Notice I said odometers plural, the regular odometer quit at 533,752 and I have been keeping up with the total miles on trip A of my GPS since June of 2014. I posted about that then. I don't post much anymore, but I believe there are a few of you on the forum that would be interested that I made 600,000 miles.
