Well, I am not at the mileage a year he is, but I do avg. @ 40K a year, up to around 50K a year. I have had my CTD for a year (a PSD before it) and have put 40K this year on it. 44 states and counting. Been stuck on 44 states actually for about 10 months. Do a little bit of everything. Transport cars, haul my race car, travel with my CTD. Sometimes it seems my truck may run for a week or so without shutting off I ran to Portland Oregon and back from Houston, almost 5000 miles round trip in 3 1/2 days. Left Thursday night, arrived in Portland Sat. morning, and returned to Houston Sunday night. A friend and me on 4-5 hour shifts transporting a Porsche 911 TwinTurbo C4. I love to drive

 

I do 40K to 50K miles a year, most of it's not even towing though. But that's what happens when I work in two different states. Sounds like if your putting that kinda miles on you should be trading out your truck at least every two years to have something as reliable as you probly need.
