Total mileage on the truck is 112,000. I've never had a throttle body cleaned on any vehicle I've ever owned. I have a Lexus with 170,000. I have the dealership work on it and no one has ever mentioned a throttle body. Didn't even know what it was until the incident with the truck.

That's because your Lexus doesn't have a throttle body EFI system, instead it as multipoint. Depending on the age and model it may be using Direct Injection.

These systems require less maintenance in fact arguably none unless an injector goes bad. This assumes you are using good quality gas.
