User blog comment:ToonRaiderStudios/Wildfire and Yeti will most likely debut at the international tour!/@comment-37646478-20190307221933/@comment-25710083-20190308013711

I personally like Octon8er, but my opinion changed to WIldfire and Yeti for the specific point you mentioned. There are 4 Double Packs, 3/4 of which only contain real trucks. With that pattern established, we can assume then that the double packs were meant for the real/tour trucks. This only then adds to the fact that we have a tour missing two trucks, and two trucks missing a tour, hence, why I think they'll be debuting.
