Bought a 2010 with 172k. One owner and serviced every 5k (have all service records). Toyota recommends oil every 5k, spark plugs at 120k, ATF exchange, coolant change, and driveline fluids changed every 30k if towing. The only thing that mine truck required besides the Toyota recommended PM was new valve cover gaskets at 120k. These are really well built and durable machines.
You can check out my build thread for PM done (The Mall Crusher). I changed radiator, water pump, upper/lower/by-pass coolant hoses, heater T’s, thermostat, alternator, starter, fan clutch, idler, tensioner, serp belt, baselined all fluids, new shocks/struts, new rear rotors, replaced front bumper sensor, PCV Valve, and replaced rear lock actuator. Did this all for peace of mind and safety since this is my wife’s daily driver and our kiddo shuttle bus. Your probably looking at $2500-3000 for proper PM now, but this will set you up well for hopefully many, many trouble free miles to come.
