I replaced radiator, water pump, thermostat, brakes and ball joints prior to our trip. Took a ton of spare parts, fluids, etc. with us. Didn't need any of them. Should have taken a fuel pump, fuel filter and heater motor with us. overall it was a great trip. 2700 miles, a hundred or so of backtracking when the road would just end. I40 was used a lot more than originally planned. 75 mph speed limits going up mountains was a little challenging. Turned around and ran for home when we hit snow west of Flagstaff. Hope to do the Eastern half in the spring.
