I’ve read on here how you maintain your vehicle’s and I’m sure you’ll have no regrets with the Ecoboost. It’s the right engine for the job of towing in this 1/2 ton class of vehicles. I was as skeptical as anyone on here about this little engine until I bought one and towed with it. Even now with Ford offering the new V6 powerstroke diesel in the F 150’s, the 3.5 Ecoboost gasser is still the top dog engine for all out grunt. I’m sure now I’d regret buying any other mill in these 1/2 ton platforms. They just seem to pull things with very little effort or gear searching. I’ve about killed my reman 351W in my F150 (burning oil) from pulling grades in the Appalachian’s in 2nd gear because that’s the only gear that had balls to get it done before I put 4.10’s in it. I can only imagine how much more the turbo’s would benefit out west in the real mountains and thin air because of altitude. Buy a extended warranty if you are worried about it, but don’t compromise for an engine that isn’t up for the task of doing what you want with little effort.This is why I’m thinking I’m going to stay with another Expedition and get the 3.5 EcoBoost/10 Speed over the 5.0. I like that my 5.4 3V has all its grunt in the mid range so it doesn’t have to scream up revs when I tow. I can let the tach sit at 3 grand and she will pull anything uphill....I think the 5.0 needs to hit 4 grand or higher before it meets what the 5.4 3V puts down at 3 grand.
