I believe there's a modern (GM?) truck out there that has a belt rated for something like 250K miles...but when you have to replace it, the entire engine needs to be removed.

Don't forget one of the latest automotive mistakes, the "wet timing belt". This is a rubber timing belt (not a chain) that runs through your engine oil disintegrating and clogging up your oil filters.
If anyone here owns a car with that system I recommend taking it to your trusted mechanic and discussing with them to do additional preventive maintenance on it.

What cars use those?
A lot of 4 cylinders and the Duramax 3.0L engine. The claim is that these belts reduce noise because chains are "loud".
Wow, yeah, it looks like the Duramax engine has a 15-year belt replacement interval that costs $10K at today's rates.
They aren't even trying to hide the whole planned-obsolescence thing at this point. Average age of cars on the road is approaching 13 years now, so someone who buys a Duramax-based vehicle will end up with a metal and plastic brick that costs more to maintain than it's worth, just because of the timing belt alone.
Build a drop-in crate EV conversion kit now. Cheap shells available soon.
That is the worst idea in the history of ideas
It's 180k miles. It's the 3.0L Duramax because the oil pump is on the backside of the engine using an oil submersed belt rather than a chain or set of gears. So you have to drop the transmission, exhaust, oil pan, and take the back side of the engine cover to replace a belt that should have been a chain. It _may_ be faster, to simply disconnect everything and pull the motor.
Source: I own one of these engines and I dread having to pay ~3k for this maintenance in 3 years. I like the engine, just not this maintenance ticket item.
In the 1955 Citroen, standard French family car of the era, the timing chain sits behind a cover about 1/2" from the firewall, the whole engine has to come out to change it.
Sounds like the Colorado. It's a reason they'll pry my S10s, GMT400 and GMT800s from my cold dead hands as they're more reliable, cheaper to service and easier to service.
