It is possible and I still get this kind of mileage on a regular basis. I don't go over 65mph (speed limit), I rarely accelerate hard, and I live in an area with extremely low population density. My drive to work is 24 miles one way, with well over 1000ft of elevation change. I get up to speed, set my cruise and literally 95% of the time don't touch my brakes until my turn off.
If you are driving in traffic where you have to slow down for slower drivers, change lanes, pass people, or get back up to speed you are wasting fuel. Unfortunately there isn't a hell of a lot you can do about it, traffic conditions will dictate a lot of your driving inputs for better or worse.
My last long highway trip was to Lincoln, NE from Hot Springs, SD. I filled up with 85 octane cat piss in Hot Springs, and took off driving conservatively at the speed limit of 65mph all the way to Ogallala, NE to get on I-80 for the rest of the drive at 75mph. I didn't fill up until I was a little east of Kearny, NE. Just over 400 miles, and the truck took on about 20.5 gallons after the fuel light came on. So it was a little over 19mpg tank average. As you might know Nebraska is flatter than a pancake, and I-80 is a well maintained road made of hard smooth concrete. The terrain plus the low friction road surface really make a difference.
I don't know why your truck doesn't get that kind of mileage (stock) maybe you are heavier on the gas pedal than I am, maybe your traffic conditions just suck. If you are driving on chipped pot holed roads that can decrease fuel economy by as much as 5-10% alone no matter how you drive. Maybe I got a factory freak, maybe I broke my motor in better than you did and my piston rings and valve seats got a better wear in.
Try driving like an old lady (minus the part where you run over people on the sidewalk) and just doing the speed limit on your drive. Let people pass you, coast up to stops even if jackasses cut in front of you. It might help.
In summary drive smoothly and conservatively when possible and you'll get better mileage.
