I had to do mine due to someone backing into me. Not too hard....the WORST part is getting the tailgate plastic top protector off. There are multiple catch clips that you have to undo 1 by 1 while putting something under the already loosened parts (start at one edge) to keep the clips from snapping back in. Some will say it's impossible to do but while hard it can be done as I did do it....and I did it alone. Probably much easier with a helper. But be prepared to contort your hands/fingers/pliers up inside the tailgate opening (after the panel comes off interior tailgate) to work on the clips - using a pliers/needlenose you have to press the 2 prongs of each clip together while pulling up on the protector...and then use something (I used a folded up towel) in between the protector & top of tailgate to keep separation as you move down the tailgate. Worst case is snap it off and get a new one for around $60 at dealer.
The rest is pretty straight forward - there is wiring inside held in places inside and at bottom with toothed pushed in clips, the tailgate handle has 4 Torx screws and 2 wired detachable connectors, the striker assemblies on each side are wired together and have push connectors holding wiring along the reinforcement beam inside. Bit of a pain to maneuver them around & out but not too bad. Also will have to debadge the decals or get new ones. IMO don't bother trying to get off or reuse the big Ram's head decal on back of tailgate. That's a pain too and the entire back side of it has tape/adhesive on it. Better off grabbing a new one for $40 - 50 on ebay.
