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.

  • I modified the unit. It's quite intense. If you have built the unit you have to take a lot of it apart but it dose look cool running along. I’m about to buy a motor for the trailer. I’m going to get a independent motor with battery and switch and hold it on the back only because it a lot of turning on the cogs.

There is this thread on Eurobricks:

Also this youtube video

There is an instruction on Rebrickable on how to motorize the truck. Please be aware that instructions are not free (I'm not affiliated with model designer).

This gives you list of parts you need to have to complete the motorization.

You can also check Rebrickable for other 42078 set and Mack related modifications, alternate and unique models with instructions (free or paid) available for each of them.
