I got a 2016 f150 xlt 5.0l and i love it, great mileage,smooth ride,and tons of power.
As for the aluminum i guess you shouldnt throw toolboxes in on their corner lol.
My buddy has had his 2014 ram 1500 for a couple years and he beats the crap out of it, has had some shifting problems and noise coming from the tranny but dealer says its nothing lol.
Other than that its been pretty good to him.
Chevs are great if you can afford them and dont mind the tires breaking off?
