You reasonably feel that your belly-pan may have been a lot of effort for naught. I'm arguing that as skills increase and finer sensitivities come to the fore that your average mpg will benefit as you make the kind of discoveries as above. I strongly feel, as also above, that crosswind buffeting will be "reduced" in re steering inputs. With no reduction in fun, however defined, will your numbers increase over time and some miles. Your work is inspiring, Orbywan, so keep at it.

Thanks once again for the input slowmover. After this trip I admit I felt like all the belly pan(s) work was for naught, but having arrived at that point and letting the disappointment dissipate somewhat, what's left is waiting for it to cool off a bit, and going from here.

I need to extend my hitch so I can tow various things with it, and I need to lower the tail considerably, and I need to finish blocking off the wheel wells (which seemed to make a noticeable difference with graydoneengineering's Frontier) and build some fairings for the duallies and the front tires.

I also need to add some vents to the front pans. Every time I look under there I am shocked to see how much better it looks like the airflow should be, so I know there is something holding back the benefits of that work. I'll do all of that and see how it does and if it still doesn't show improvements, then I'll rip it all out and throw it on a bonfire.
