Welcome to the site. I am fairly new to the site as well and am loving it. The question is where to start? Some of this depends on where the truck has been, was it used daily, regularly, in frequently, or is this a ressurrection. In general I would start with simple tasks like changing fluids, engine oil + filter, flushing coolant and new thermostat, transmission and rear end gear oils. I would also change fuel and air filters. If money and time allows- a tune up - distributor rebuild, spark plugs and wires. Grease the drivshaft if the u joint have zereks and the front end steering and suspension. Consider belts and hoses, heater hoses included. As I type this I am also thinking about items that pertain safety- tires- tread, sidewalls, pressure, steering, and brakes. Good luck Bruce
