As the temperature starts dropping, I was looking for the cord for a block heater on my '15 Chevy 1500, and cannot find it. I bought the pickup in Wyoming so I would think they would have one on it. I looked everywhere and cannot find one.

Should be able to check your window sticker/ build sheet, it would be on the options side (right side) of the window sticker. I know most 1500's don't come with them but you are up north so maybe they do just come standard

Bet no one ordered a block heater on it, there are MUCH better options out there anyways as the factory block heater won't come on until it gets very cold, best bet is to cut the lower radiator hose and install a lower radiator hose heater. They work great, are much hotter then a block heater and circulate a lot more coolant. Quote

This one was used, but the last two pickups I bought were new and had them. It's an LTZ, I don't see it on the window sticker, I don't think it's the original window sticker since it's used. And also some of the LTZ options aren't on the window sticker and it definitely has those options.
