Hi there! I'm new to the forum and new to diesels as well. I've been doing a lot of research but I would like to get everyone's opinion on the newer 6.7's. I have my eye on a 2011 f250 fully loaded, lifted with 38's and 26000 miles on the clock. Is there anything I should watch out for as far as reliability issues? Are the newer motors holding up well? Does anyone here do the deletes and not worry about warranty issues? Any advice would be greatly appreciated! Thanks!
