Big Service Day(s) for the Truck: Oil+Filter, Transmission, Engine Coolant (swapped out nasty reservoir housing too), Transfer Case, Differentials, and Brake Fluids all changed. Air and Cabin Air Filters changed (earlier this weekend, I don't know why we need 10 screws for the air filter housing but so be it).
Knock on wood it was given a clean bill of health, will send the oil in for a sample next time I change it (3,xxx miles I usually do). Huge Relief knowing it's pretty solid after the lack of service records. I have an aftermarket rear bumper, wanting to go back to OEM, quoted $9xx for all parts/brackets needed. Not terrible to be honest. Will most likely order that.
Anyways nice to keep knocking stuff off my list: fluids, tint, tires, beauty rings, catch can, dash cam, mud flaps. Next/Last things are Baja Designs onx6 light bar for bumper, IGLA, and maybe speakers - this HK system isn't really blowing me away coming from a crappy Toyota tundra stock system.
