UPS trucks are set up for a 20 year life span of daily service. Do you think those little off the shelf GM cutaways are designed to do that. Perhaps in a no road salt non snow belt environment you might make it to double digits little chance elsewhere.
The only thing that gives them a 20 year life span is the aluminum body.
And if you’ve ever looked under a Fedex P1000 it’s evident that parts are made to be replaced.
Stood with a mechanic as he replaced a clutch in a ‘98 international. Hour and 45 minutes start to finish.
So what are you really talking about with the cutaways? Will they last 20 years? Sure they will. Most will probably move on from them far sooner because we don’t have the “in house” mechanics that UPS has and maintenance costs outweigh practicality.
You weren’t implying that those 20 year UPS trucks didn’t need maintenance and parts replaced were you?
