Dad bought his 2013 new and had not a single one of these problems. It has zero rust or any of these to this day. Maybe it's an owner thing. The 5.0 is straight lol. It feels like "a much better truck" in that it's lazy and lags. What's the eng have to do with rust, a rear defroster, shocks and struts, bumpers, belts, and a parking brake? El. Oh. El. Nothing. That's the answer for inquiring minds.
There's good info from an informed owner and honest to boot. The MPG's is perplexing. We see, on long vacay's, 21-24 MPG. With towing a 2,500 lb trailer PLUS load we don't hit NEAR 11-14. Something may be off or just YMMV. Shrug.jif.
I've known both of these fellas for a very long time and I know they take great care of their vehicles. The rust issue HAS to be from buying used and p.o. treatment. Dad's 2013 still has not one single rust spot on the body or frame and it's parked and driven outside its entire life.
I know, I know. It's dad's truck, not mine. I know this is kinda a "ford's suck" environment. I just don't see it personally. We beat the ever loving shit out of trucks. We've had Chevy's, Ford's, Dodge's, and Nissan's, from a VAST age/year range. In our experience, aside from the vintage/classics ('49-'78) the Ford's have never let us down (and even our vintage/classiv Ford's haven't let us down, saying that all the old trucks are fairly equal), always performed, and NEVER been an issue with actually doing truck duties on the regular. YMMV.
