I wonder what the fuel efficiency impact will be if I added the 4K tow package to the AWD system. I assume the increased towing capacity of the 4K tow package is being achieved by using a shorter final drive ratio. If that's the case, there will be an efficiency hit at higher speeds, won't there? Although at fist glance it sounds appealing to double the towing capacity for under $800, but the appeal of the Maverick to me is partly its fuel efficiency. If the AWD's fuel efficiency is affected by the 4K tow package, then I might as well stick with a 4WD Ranger if I really want the larger towing capacity.
