I did a bit of research, and this is what I found: This article says about 20% of vehicles sales are to fleets. It says vans are the most popular fleet vehicles. It syas "light trucks" (which includes vans) outpace cars in fleet registrations at 22.5% vs 17.3%. https://www.autoserviceworld.com/fleet-registrations-continue-to-rise-in-north-america/ https://www.autoserviceworld.com/fleet-registrations-continu... Based on that data, I see strong evidence that the F150 is not boosted over other types of vehicles. I certainly found nothing to support the idea that it is, and if it is, it does not seem to be a strongly dominant consideration.
