Just drove past a 4th gen, help identify the trim package?

[MyExplorer03v8Lim]

On the left side rear the only marking I could see was "EXPLORER". On the right side I couldn't make out the text, but there was some silver/ metallic text up top and directly under and connected to it was some red text that looked like R56. I could be wrong on that.

Can anyone help me identify it based on this info?

Thing is, it seems only the 06 and 07's have that on the tailgate.
all of the 08-10's just say "4x4" (if it's a 4x4)
