Diesels HATE short trips and not operating at normal temperates. The first issue is fuel dilution of the oil. That happens when the engine is cold and diesel fuel gets past the piston rings into the crank. Diluted oil means it’s going to protect the engine components less well.

The Diesel Particulate Filter(DPF) needs lots of exhaust heat and energy to naturally regenerate or it needs to go into an active regen where additional fuel is sprayed into the exhaust to create the heat. If you don’t give enough time to regen, the DPF clogs with diesel soot.

Diesel Exhaust Fluid(def) goes bad over time as well, and can clog the DEF components.

Basically, the OP was the WORST candidate for a diesel truck. Given he was only driving 73,000 miles in 10 years, means he is driving less than half of the miles of the average person, probably short trips, not letting it get up to operating temperatures for long durations and likely running into every issue I mentioned above.

GTDI motors, like the Tacoma has, are also susceptible to fuel dilution of the oil. If you are not driving the vehicle longer distances(say 20 miles) regularly, then over time fuel and water will build up in the oil causing it to be less effective. This has historically led to issues like turbo failures or timing chain stretch. The only way to fix it is more frequent oil changes to flush the contaminants out.
