Keeping my fingers crossed! Traded a perfectly good 2003 7.3 for a new 2005 6.0 lariet yesterday. After having purchased many new vehicles over the years, can't believe the deal I got on this bad boy. So, the question is, I have a trip planned for next weekend to pull my 8000 pound camper to Tennessee. How many break in miles should I try to get on the truck before it is safe to tow?
