This is the 2017 Super Treasure Hunt truck. Apparently, the cards no longer identify the casting as a Super Treasure Hunt and there isn't corresponding Treasure Hunt. The "TH" along with the Spectraflame paint and Real Rider wheels denotes it's a Super Treasure Hunt.
Keep your eyes out in a few weeks. There are a few showing up on EBay shipped from Malaysia (probably smuggled out of the factory).
