I believe he was able to get rid of all the debris from this nose haha; as for the 2500, please have a seat, it's gonna take too long to explain.
WT in Mexico is called "Silverado"; if it's the single cab with the V6, it gets the 1500 badge. If it's the single cab with v8 (2wd or 4wd), double cab (only 2wd) or crew cab (2wd or 4wd), it'll get the 2500 badge (although it's not an HD, it's the 1500 at heart.
Any other trim is called "Cheyenne", and that's what you get with the Z71 or High Country versions.
