I'll bet that it wasn't the fact that GM wouldn't provide engines, it's that furd would provide them cheaper. Their notorious for that. that's how the sell so many f 150s, they undercut the price on fleet sales, that's why you see so many f/e 150/250s used in fleets. The medical supply company that my brother-in-law works for had some e 250s, because they were cheaper. Turned out that they cost more in maintanance than the Chevy (ball joints wear fast on them). They now have G 3500s and have no maintanance issues.
