I found this little gem at TRU when I got Soundwave. The scale looks perfect to me aside from the wheels. It was attached to a very simplified cab which played some truck noises and an awful 80s-style guitar solo and blinks some lights. I set the electronics aside for now. I grabbed Magnus for this quick shot because he was already in truck mode but it obviously works for Prime too. I missed out on those "Hardcore Truckin" trailers everyone ordered from Ebay when the Classics were released, so this makes a nice substitute. It also helps that you don't have to pay shipping. This was $12 at TRU, a steal with the electronics. They were packaged in an open box in 3 different colors. They were located between the R/C cars and the knockoff GI Joe toys in my TRU. Obviously I will paint this grey and contact Reprolabels for proper decals. If you still need a Classic Trailer its worth a look IMO. Enjoy.
