I had a little over 25k miles on mine when I traded it, and that was done in 13 months. It was my DD and TV, but bought specifically to be our TV. Lifetime ~16 MPG with about 7% towing. It was the 2nd favorite vehicle I have ever owned. Had the intercooler condensation issue with it, but it was fixed in 30 minutes at the dealer while I was on a moving trip.
This was the first turbo gasser I owned, and was very pleased with it. They will be a part of the future for sure as it improves engine efficiency quite well if you keep your foot off it.
I would definitely buy another, but it will be along time off. Our next TV will be very inexpensive should our trailer not sell in a year.
