Stopped by the ford dealer today they had 3 2015 F-150s in stock 2 3.5 ecoboost and a 5.0 all xlt trim. I was suprised the payload of the 3.5's was 1920 lbs. 1920 for a standard payload truck they did...
"Power slide rear window"... I don't think I've opened the rear window in my F250 in over 5 years - I just opened it when I got it to check it out. I wouldn't pay extra for that option if you can avoid it.
