I'm one of those old fashioned guys that will not buy a full size truck with anything other than a V8. They are relatively slow turning under stressed units that have and hopefully will continue to give good service and longevity. Yes I know forced induction and smaller engines are what the manufacturers are doing but the high temps and high stresses don't instill me with confidence.
Let me start this by saying I love my EcoBoost and that the V8 vs EcoBoost argument can go on forever. That said...
You can't just say a V8 is more reliable because it doesn't turn as many RPM's as a Forced Induction V6. In fact the V8 in the F150 was originally a mustang engine that was designed to make power in the top end of the RPM Band. Took a quick look, in the 2018 model peak horsepower is at 5,750 peak torque is at 4,500. If you are towing anything heavy /w the 5.0 you are going to be spending some time in the upper RPM range. Not that its necessary a bad thing, the engine was designed to do that, just like the 3.5 V6 was designed to handle making power through the use of turbocharging. Just depends on how you want to make your power.
The great thing about the EcoBoost that you are missing out on is the torque is delivered at a much lower point in the RPM band. It's not like I am screaming along at 3,500 RPM on the highway, in fact its exactly the opposite. Cruise at 80 /w the 3:55 rear end is around 2,100. If you hit a hill it doesn't downshift, just adds some boost.
Where it does lack is in engine braking. The 3.5L just isnt enough engine to really slow down by itself /w a boat behind it. But hey thats why we have trailer brakes right?
