my 04 6.0l 2500 gas has 131k now and still running stong but I have pulled 30 foot trailer with 2 sami on it.. and also have 18 steel deck with 2 sami on it..pull both nice been to Harlin a bunch of times with no issues.. I have had the water pump go out under warrenty and changed out front wheel bearings.. other wise a good truck...
bad is the trans is only 4 speed and kicks into over drive at 4500 on some hills...
would be great if it had allison!!!
