So far, I'm liking the diesel. It pulls better than anything I've ever owned and gets great MPG. Only three weeks and 3,000 miles in but don't regret not getting gas now. We'll see long-term how reliable it is, but so far, the best truck engine I've ever had. With that said, I wouldn't want it for short hops around town but it's great for the 30-minute to 2-hour drives I normally do.
