She made it to San Diego. However I've been having uphill overheating issues. I replaced thermostat in South Carolina, which helped, but todays climb through the Rockys into California with 90 plus heat was too much. After several pull over and cool down sessions, I unbolted the hood for extra airflow, and was able to continue the climb, although she still got warm, no boil over.
The head gasket has had a super small leak since I got truck, so I'll be tearing into motor when I get home.
