Just be aware that the hitch on the 2013 isn't suitable for weight distribution. A hitch made for Lexus IS and will fit the 4Runner. With the proper hitch and sway control that combination should work well together.
Eh...lots of debate and assumptions made about this.
Manuals vary from print to online and multiple people claim to call Toyota directly and get the ok. Toyota claims they have nothing in writing to say otherwise. Inaccurate manuals? Believe the person on the phone? That's for the owner to decide.
But the worst is everyone assumes because one style hitch is not bolted directly to the frame, its instantly not suitable for a WDH with spec tongue weights. That's just hogwash IMO.
But the debate ends with a hitch change, one that is mounted to the frame. Except people then think its ok to ignore the owners manual and assume the new hitch ratings are now the new tow ratings for the 4runner. They are not. The frame mount hitch will only give you peace of mind, not a high towing capacity.
OP - I think you'll be fine, and I would absolutely use a WDH if you'll be towing any distance. People are always amazed how much better towing is with a WDH, and a 300-400lb tongue is more significant for the 4runner than you may think.
