I've been window shopping as well and got intrigued by the F-150 ecoboost.
More towing capacity than my Tacoma (6500lb vs 11,300lb) , and that means I can get a bigger alloy boat (
)
My searching hasn't turned up much, other than this forum
http://fordecoboostforum.com/ where they
discuss the ecoboost in multiple Ford products.
In the 3.5L forum, some new owners discuss some minors issues like turbo spool up delay, and some bad coil issues....most of them seem impressed with the power. Some are racing them for laughs. Some complain about fuel mileage, but they may have their foot in it.
My son's landlord got a new F-150 Ecoboost Platinum fully loaded...almost $60K here in Canada .. he says it has unbelievable power and with twin turbos, worries the back tires might not last long.
His first highway trip was an issue.. going up the Coquihalla highway, a steady climb from the coast to interior, he lost all the tranny fluid, just leaked out somewhere, and you can guess how long it lasted... Ford took another tranny off a truck on the lot and replaced his without question. Other than that , no issues, and he's looking forward to towing a 5th wheel with it next summer.
Another friend test drove the F-150 and ended up buying a used F350 Superstroke to tow his trailer...he felt the F-150 was just too soft a suspension, and that it suffered a bit of corner sway...probably not much different than the light duty car suspension in my Tacoma... nothing a couple of Air-bags and some stiffer aftermarket shocks couldn't fix.
That said, in spite of all the testing Ford says they did, my mechanic tells me not to buy new engine technology in the 1st year, as there are always design improvements after they get real world service data. but I'm watching closely...I want bigger tow capacity, and better fuel economy, but I don't need more payload, and I'm not keen to go back to diesel...so the F-150 is definitely on my radar.
