The 2.7 is completely different than the 3.5 in terms of fuel economy. My suspicion is a 3.5 4x4 with any sort of max tow or payload package isn’t going to see dramatically better fuel economy than a 250/2500. Looking at Fuelly for a 2019 F150 with the 3.5 the average is right at 15 MPG. That of course is not broken down by cab, driveline, or other specs.
Ride quality on the Ram 2500 is really good, especially with proper tire pressure. The only negative for me is the fuel economy sucks, sitting at 12.6 steady right now. So a 3.5 Ecoboost would probably get me 1.4 to 2 MPG but I would lose the solid front axle, long bed, tow capacity, and payload. At 10,000 miles a year and $3 a gallon for fuel it’s about $380 extra to drive the 2500.
I absolutely love mine. I've owned a 2013, 17, 18, and 19, all 3.5 eco's. Have driven many 5.0l's and they're just absolute dogs compared to the eco's.
Yep, it just sounds like POO
Co-worker of mine is always **************' about how his 3.5 sounds, especially when I drive my 6.2 to work![]()

?When I punch the throttle it takes off like it was fired from the barrel of a howitzer. How it sounds is irrelevant to me.
I certainly didn't buy my 6.2 to win races.
Its a damn truck afterall ?
But a 3.5 ecoboost, especially on tunes, can be very good times ?
I guess i'm an old man at heart... I like a big noisy V8 (summer car is a 2019 Mustang GT that is... Shall we say delectably loud), but there is nothing worse than daily driving it. Love how quiet the eco is.

I enjoy how the expected "buy a 3/4 ton rather than HDPP halfer" became an "EcoBoost is superior" thread.
I haven't seen the OP in pages of responses lol
Pppssshhhhhh (that was a turbo joke)Everything turns into a turbo vs na thread

That was my experience too, I got a loaner F150, King Ranch, 3.5EB (go figure) when my Ranger was getting a minor body repair, I hand calced MPG and was in the 17-19 range over a couple tanks, trip meter was 18-20, which is about right. Mixed driving.15 non-towing sounds low. I reset my 2nd trip meter after my last towing trip in October, and my overall MPG, non-towing, has been 18.2. That's AFTER I calibrated the on board computer (there are instructions on the F-150 forum on how to do that, it's pretty slick.)
Virtually all of my driving is urban/suburban (20 mile round trip commute to work) and I have been averaging right around 17 on Winter gas.
Towing MPG is the same or a tad lower than what I was getting in my '04 Suburban, 9 - 11 MPG when towing a high-profile travel trailer over an 11,000' pass.
The difference is that the Suburban made it to the top in 1st gear (literally, in 1st gear) with the engine screaming at 5,000+ RPM and going MAYBE 30 mph.
With the 3.5 EcoBoost I'm in the left lane, going 65+ trying to pass slower vehicles and the engine isn't even breaking a sweat.
