I'm new to the forum... I have a 2012 F350 Lariet 6.7 Crew Cab DRW that I bought new in 2012. Before that I had a 2004 F350 XLT6.0 Crew Cab DRW.. Bought both new.. Had a lot of the normal problems with my 2004. egr cooler, oil cooler, turbo, fuel injectors, rear end gears, y pipes, etc. Spent a small fortune on it even though we did the repairs but I still loved it.. Loved the purr of that engine.. Even with all of its problems it never left me sitting along side the road.. I put 160,000 miles on it before I traded for a new one.. My new one is ok.. Lots of bells and whistles that I never use.. 36,000 so far on this one.. Mileage sucks, and it just doesn't have that diesel purr.. Sounds more like a sick gas guzzler. I really liked my old one better, but I still wouldn't have anything but a Ford Diesel... Love my Ford Diesel Duallys!
