Mack  Dip & Dunk is interesting in that he’s not a color changer per say but he carries tubs of water for color changing – one hot, one cold … I cannot foresee any problem arising from kids driving around tubs of water in the house. 🙂

Plus in CARS World, is it really a good thing for CARS to be in a tub of water with the lid closed …

There is a listing for 2 other transporters. Probably Dinoco-King & HTB-Chick Hicks?  Though we’ve never had a plastic HTB or Dinoco cab release, have we?

Color changer singles are coming back so they should probably be released at the same time.

Amazon does have Mack with Dip & Dunk trailer (final version has red lids versus these proto pics).
