I have a 2WD 2019 F150 with the 5.0 I use to tow my horses around. With the tow package, I think its max is 12900lbs and it does a hell of a job on stuff in the 6-9k range but get up in the max range and it struggles a bit. I would say it gets about 8-12mpg depending on what we tow with it. I think it’s rated for 19/21mpg just on its own. I get about 17/19mpg just driving it around.
It lives a light-duty life hauling horses down highways and South Texas caliche roads, but I am happy with my f150 most days. I think when it comes time to replace it I will go back to the f250 for the higher towing capability but stay gas only because everything we run is gas.
Hopefully, my experience helps, have fun truck hunting.
If it’s good enough for the woman he rapes it’s good enough for Ukraine.
