Their truck is an 03 or 04, I can't remember. So it's an early engine of the 6.0, where a lot of the problems were. The reason I don't want a 7.3 is the manual locking hubs, when going between stops, I always put it back into 2wd and I'd prefer not to get out to have to manually lock/unlock the hubs. They're also very hard to find in good shape for a decent price around here. As for judging an entire brand off 2 engines, that's half of their diesel engines, if half are troublesome, that's not a great ratio. A 6.7 is definitely not in my budget this year, 50-60k, not going to happen when it's going to be a work truck. If I were to buy a dump truck right now, if I could find it, it'd be a 7.3 w/ aluminum bed and it'd be used for salting.
