Buying American is a sentiment I won't knock on. However it's coming pretty close to being inarguable that the Japanese are building better vehicles than Americans are.
Trucks have always been easy to work on, by the way. Pickups have always been 5-10 years behind passenger vehicles in terms of automotive technology. They were late to get rid of things like carbeurators, throttle body injection, mechanical fuel pumps, a prominence of vacuum actuated devices, etc.
