I'm at 220k with a heavily modified rock crawler. It gets beat on. 35s, air locked 4.88 diffs, 3/8 steel full skid plates, shorty headers, big steel bumpers, dom sliders, rcv cv axles, diamond plate driver side cargo window, dual battery, high output alternator, pedal commander thingy... I wouldn't say I thrash it, but a reasonable person might say that I do. I did once send the front diff into the oil pan.
I fully expect to reach 1 million miles with this engine.
The weaker tundra 4.7s have done it. I would think hotshotting is harder than driving 100 miles to do a 30 mile rock trail and driving back.
I swap all my tranny fluid every year, all 12 quarts.
I check rear diff and transfer case fluid regularly. I pop one of my axles out often enough I don't worry much about the front diff fluid. Usually looks clean as it runs down the pavement
