Aeronerd Update:

The high end gain of worst to new average is 66%, and those worst are from headwind without the mods, and the mods seem to mitigate them.
We could tweak that with adding All Terrain tires that I run at 30psi that coincided with my aeromods, over un-modded with All Seasons that I ran at 32-34psi, which the industry estimates an mpg loss of 3% with matching psi- so maybe 4% mpg loss for the A/T tires. So the actual gain could be adjusted up to 44% at the low end, and here is where I question reality…(66% + 4%) 70% gain in strong headwinds.
Welcome to hot SLC!!! Interesting comments on aerodynamics/gas mileage/tires, etc. The evening sky at the ranch is almost as gorgeous as Webb telescope’s Space pictures. In the depth of his quiet soul, your dad drank in that beauty….while learning responsibility and being a loving steward of the animals entrusted to him. I am so pleased that you are embracing the legacy he left for you……….. The interior shots are so comfy………leather furniture, a white recliner, new lamps, drapes. And the cats thanking you with mouse gifts …. treasures to show they’re earning their keep in the Montana environment they love….proving their worth so that you’ll be sure to bring them back with you on your next visit.
