1997 Dodge Ram 2500 4x4 Driving movie 2

Solid truck with 307K miles. Drives great, no overheating or smoking. Starts easily, and shifts great. 4x4 working good. Front end seems good, goes nice and straight down the highway. Brakes working good but a light pulsation under panic braking from highway speeds. A/c is pretty cold. Lights and locks all working.
