Funky tailgate and amazingly clean! I did a little search and got some pics.
the first (blue) is a mexico tail gate.
the second one (red) is just like yours and supposedly an argentina tailgate.
The third (red) is our USA tailgate.
Never seen the one you have until I just found the pic of the alleged argentina gate. Interesting. I like it!
Borrowed the pics of course from others on here
