After looking at all these 1/2 ton numbers, I feel pretty good about my Ram 3/4 diesel numbers. Local driving which includes city and short highway driving I'm getting around 18/19 sometimes 20 if I keep my right foot under control. Interstate driving where I typically run 75/80 depending on speed limits, I've been able to get 25+. The only real weight I've towed with it so far was a 9000 lb camper for about a 150 mile stretch on interstate. I kept the cruise on 70 and got just over 15 mpg. I do tow around a SxS back and forth to deer camp several times a year and that brings it down to 17/18. I'm sure these numbers will change over time as I don't have 15K miles on it yet so it's not even close to broken in. I know many like to rib Ram owners, and I don't mind that at all with these numbers. And since my Ram cost 10K plus less than a comparable Ford it was an easy decision for me. Don't get me wrong, I liked the Ford over the Ram for various reasons. I just didn't like it to the tune of 10K more.
