The vast majority of people with half tons don't tow. And of the small percentage that do, they don't tow enough to need the upgraded radiator. It seems like a silly thing, but for Ford they're always looking for ways to reduce costs to stay competitive with the competition on price. One of the ways they do that is by decontenting vehicles to reduce the advertised starting price. Ford will nickel and dime on everything, which is how you end up with important upgrades that cost $1,000 on a $70,000 vehicle. Porsche and Audi also employ this strategy. Before 2018, HD Tow upgrades were standard on all Limited and higher trims. I guess the marketing people got in the mix and decided that they could earn some extra margin by making it optional for those that really wanted it. Ford sold something like 40K Expedition through Q2 of 2023, that's up to 40M in revenue for the HD Tow upgrade for the first half of the year. It doesn't sound like much for a company this size, but there's a reason they employ bean counters.
