Same ladder frame, same body, same CV Axles, same coil springs/struts, same doors, same windshield, same gas tank, same driveshafts, same floor pans, same radiator supports and body mounts, same transfer case, same differentials...ITS THE SAME TRUCK 03-17! The only differences are some pieces of plastic on the interior and on the front. What really makes up the truck is the same. BTW 03 sales sh*t on 15-17 sales, oh and they sh*t on 2018 sales too. The 2nd gen was an amazing truck with RECORD HISTORIC EXPY SALES! to pick on this is to pick on the entire model. IMO they are the best looking to this day too.
