That can haul a livestock. How about 12? Or would you like them to make more trips (with proportional use of gas and risk of accident)?
As for F150s hauling nothing, that’s kinda my point. There’s a market above it that actually does work (F250 and up), and there’s a market that ought to exist underneath it (what used to be the Ranger, which is now much larger). You’re targeting the wrong group by focusing on trucks that haul 10,000 lbs.
