Here's my first attempt to use all COTS items and parts from the new product line to make a drivetrain. It could be simplified a lot, and the big complexity is the bumper mounts which I was lazy with. Other than that, it's relatively simple. I put in the correct weights for each object and Solidworks is telling me 37 lbs with everything pictured (20 lbs of which are the transmissions + CIMs).
