I have been wanting a diesel for some time. I've spent a lot of time on this forum learning what to look for, what the problems are with the 6.0 and what to do about problems. I had decided on an 07, cc, 4wd. My problem is that I would only be able to drive a truck an average of 2 or 3 days a week, some short trips, 15 mi. one way, some longer, 100+ miles one way. I tow an 8000 lb 5th wheel, maybe 4 or 5 times a year. If I get a "new" truck, I expect to keep it 10 yrs. or more. I would put 12 to 15k miles a year on it. I have searched for posts on how many miles typically expected out of a 6.0, but have not been able to find anything. A want a used 07 with close to 100k miles and I need it to go 250-300k. I understand the need for regular and timely maintenance and would try to do any work myself. (done a lot of gasser work) So, am I safe with a 6.0 under the above conditons.
