Dealer let me have a Raptor for a hour,(that was great),got to do city and hwy driving,5.4 is not enough,truck work hard getting to speed,and at 60 mph trying to pass was long,mileage seemed not great,dont think the 6.2 will help enough,test drove a new dodge ram,it smokes the raptor,so i went with the dodge,and saved over 10 grand ,just my 2cents.
