So what is there no third party trailer for CW Prime? Like at least a nice adapter for using one of the ones for Classics Prime would be super. So I figured I needed to make one for my Optimus since he just seemed odd without one. I came across a pretty plane Jane Machine Wars trailer that was missing a ton of bits and accessories, but I felt the overall look lined up with CW Prime. I repainted it a nice metallic aluminum, redid the wheels with the lower legs of a junker figure from the same series, and then added a trailer hitch that fit properly. It still need Autobot symbols and I'm added more details like the stripe on the side and painted in tail lights. Added bonus, even with as barren as the trailer was, it still makes a great cannon mode.
Added a blue stripe down the side and some tail lights, also had some spare reflector looking stickers that looked like Autobot emblems.
