I wanted to convert the main vehicle in set 31101 into something a minifig could ride, since I like sticking minifigs in vehicles! I liked the unique suspension system of the monster truck, so I decided to just modify the top and keep the frame as is. I also converted the smashed micro car into a riding lawnmower. I only used the pieces that came in the set.
To follow along with my tutorial, first build the main monster truck build with the set instructions, then remove the appropriate pieces to match the video when the tutorial begins (from second 13 to 16). I included shots from a few angles so you can pause when you need to. To build the riding lawnmower, take apart the entire smashed micro car and follow the tutorial.
I hope you enjoy this mod/alternate build!
