Read on the RV Daily report which cited Business Week as a source that there are now five lawsuits seeking class action status against Navistar (International) because of design and manufacturing defects in the 6L motor. Covers the years 2003 thru 2007. Ford wasn't mentioned in the blip I read. Suits are in California, Arkansas, Mississippi, Tennessee and Utah. This could have huge implications. Have a buddy I fish with who has almost 100K on one with few issues and no major ones so they are not all bad. Just glad I do not own one.
