8.2 mpg over 30,000 miles. Best fill-up 11.8 (big tailwind run) worst in the low 5's (climbing passes or fighting headwinds), but individual fillup mpgs are not particularly reliable.
7000 mile average is a pretty good base for expectations. You aren't going to get into the extremes unless you get those driving conditons. My several tankfuls over 10 MPG all involve running at highway speed with 10-20 mph tailwinds all day, you get those conditions on the plains. But then it comes back as a headwind that gets you struggling to maintain 55 mph in overdrive, or a crosswind that keeps you off the road for a day.
10-12 mpg is believable to me for someone in a 8000 pound B+ with 75-80% of the frontal area and a more aerodynamic cap. An E-250/350 based B getting 12-14 MPG is also believable, my E-350 van has averaged 15 MPG over 8000 miles, gets 16+ routinely on the highway, has done as well as 18 MPG cruising 50-55 mph on rural roads.
It might get better as you learn how to make it better. Don't know what babying means to you, but if it means you never drive over 55 mph you should be doing better than 7.6 if your roads are all flat and you down have any towns to slow for, or stop and go.
