I just got back from a 4k road trip from Portland-Boise-SLC-Arches-Zion-Las Vegas-Death Valley-San Francisco-Crater Lake-Portland.

Leaving Vegas heading south it was 108ish and with this one long steep hill and AC my temperature got up to 217. Same number leaving Death Valley. It had me nervous, but she kept trucking along. Still very happy after 5 years!
