Not incredible mileage returns, but I got 21.7 mpg. Weather was nice, low 90's, I stayed above 70, less than 75 (or at least tried). Two passengers, and luggage. AC was going and set around the mid temp range. And hit some stop-and-go traffic, thank you CalTrans road work and thank you, no reason at all.
I tell you climbing out of Vegas, going over the pass, that's one hell of a climb, was able to maintain 65 on the climb out.
This was the Liberty's first trip to Vegas and it performed flawlessly.

Nice.
