This is why my fleet trucks are used market that I send out for refurb. It makes a lot more sense to me to go out and buy older vehicles and dump a few thousand into them rebuilding Driveline components, interior, Etc versus buying new. Older platforms generally speaking ate proven if you buy smart.
That, and I only buy manuals, which really cuts down the truck options for new market. There's a story as to why I'm banned from the local Fleet Sales dealership involving manual transmissions, but that's not for the internet.
