We just got home from a 2700 mile road trip.
Seattle - oakland - yosemite area for some fly fishing - over Sonora pass to Reno - Ogden - Boise & home.
Average speed on the highway was 73 mph & 18.6 mpg overall. The pathy seems to find it's stride at about 85mph when there are no cops around.
This is the 3rd long distance trip in the pathy & I'm still impressed as to how comfortable it is & how well it runs.
