The W3DTankDraw should be the best option for you. There must be some reference to parts the TankDraw does not support, like "TireRotationMultiplier" or "TireBones".
You could use the W3DTankTruckDraw module instead. Check the quad cannon. It offers both Tank and Truck Draw in one module.
And you don't need the UVW Map modifier, simple unwrapping is enough. I think he meant the tread moving animation. In fact these aren't anims but moving textures. So they have nothing to do with animations in the way you created them when constructing etc.
Edit: Well someone was faster
