Here is a really good resource for mileage and fuel cost per mile. The participants are less inclined to brag about their mileage, I believe...

I got 12.2 mpg, while they got 16.9 mpg. But I only paid $0.06 per mile more for fuel. On a three-thousand mile trip, that would amount to $180 more for me.
Hope that this helps somebody...
Mark, thanks for posting this and bringing back this thread.
We keep an old fashion vehicle record book to record work/maintenance and each fill up along with mileage. I watch mileage trends as one of the indicators of vehicle health.
We drive a 2003 Ford Ranger 4x4 with the 4.0 V6, auto trans and 4.10 gears. It has a custom Deaver leaf spring pack and it came with Bilstein shocks. We bought it used a couple of years ago and it turned over 70,000 miles on our last trip. Our camper is a FWC/ATC hybrid Ranger II. We live simply and travel fairly light; we're not much into toys except for our backpacks.
This combination has been very successful for us as I believe our trip reports show.
Here's the stats from our last four trips. This may be a little different as in previous posts I had averaged the mpg for each fill up for the trip. Here I have done the basic math.
Idaho Trip July 2011
miles driven: 2251
gallons: 125.84
mpg: 17.89
Nevada July 4th 2011
miles driven: 893
gallons: 49.55
mpg: 18.02
Nevada Memorial Day 2011
miles driven: 753
gallons: 43.26
mpg: 17.41
Spring Break 2011
miles driven: 1780
gallons: 103.55
mpg: 17.19
We burn unleaded regular and drive conservatively for mileage. As much as possible no Interstate highway travel and 60 mph is max.
