Adding Power Functions to LEGO Mack Anthem Truck (42078) Does anyone have experience adding Power Functions to set #42078 LEGO Mack Anthem truck?  

It’s a Technic set, but only features manually actuated functions.

I have seen it motorized on YouTube, even though a Power Function option is not mentioned on the box. Any details on how to do it would be very much appreciated.
