Moab trip with mileage report

Here's a detailed spreadsheet of my fuel mileage over the course of a 4,000 mile trip to Moab and the southwest. First, the disclaimers:

I was pulling a 1,000 lb trailer (teardrop) with my bicycle mounted on the front of the trailer toolbox. Not the best aerodynamic use, but very functional.
I have different tires from stock. I'm running Firestone Destination M/T's in size 245/70/17.
I have a Yakima roofrack and was also carrying my Easy-up awning on top. So you can imagine it's not the most aerodynamic rig on the road.
Here's a photo of my rig:


Here's the spreadsheet of my fuel utilization:


It's mostly self-explanatory. There may be (is) some "rounding up and down" in there, but the differences are tiny. I also added in the tire diameter calculations to make it a bit more accurate. The new tires are 3% larger diameter than the stockers so I've reflected that in the adjusted totals. I have also added a few notes and another category (Octane rating) to help get a better picture.

The MPG adjustment calculates the fact that I actually traveled 3% farther than the odometer said. Therefore, my mileage overall was 3% better than the raw calculations show. I've added in that 3% (.48 MPG overall) at the end of the spreadsheet.

Overall, I am much happier with things now that I've done the math properly. I collected receipts so the numbers are very close. To be fair, the trip was pretty much a headwind slog in both directions: going across Nebraska and returning across Oklahoma and Kansas. Whether it is just my bad timing or it is that windy all the time I can't comment on. Suffice to say, it was mostly "beating to windward" in both directions. My overall number (MPG) is not nearly as bad as I imagined it to be on the various fuel stops. Actually, it's a little bit better than I had hoped for. Enjoy....

I did the Gemini Bridges trail and the Jug Handle Arch trail as well as a bunch of just desert roads. It was fantastic.
