I traded my 2002 Explorer 4x4 V8 Limited in for a 2012 4x4 Limited, both fully loaded including factory tow packages. I can say for a FACT these two vehicles are in no way shape or form even remotely related to each other, period. The 2002 is a truck, the 2012 to present is a Flex. When I bought mine (unchanged to date), there were more Bently's on the road in this area for at least the 1st year, people thought it was a Land Rover.
Never had a problem towing the boat in either, but there sure is a difference in power. The V8 feels way more secure power-wise where the 2012 makes up for it with 6 speeds fancy shifting routines and assisted power train braking.
