Just hit 40k miles

Just had 40,000 miles on my truck, all is well. Over the few years I’ve owned it, I have change oil every 5000 miles or Mobil 1.
I change the front and rear differential and transfer case with Ravenel oil around the 30,000 mile mark. Change the transmission fluid and filter at about 35,000 miles using WS fluid, also did a brake fluid flush and a coolant drain and fill. Within the first year, I also picked up a practically brand new set of 18 inch off-road rims with the Michelins on them, will go to KO2’s with a leveling kit in another year or two.
Everything is great, truck has been flawless
