I believe this sleeper is called the Penthouse. Able Body did build sleepers for both FORD and MACK. It closely resembles the sleeper in the Superliner kits, but there are differences.
Thanks Chucky. This is only the second 1:1 real-life version of this trailer I've ever seen. The spare tire carrier is different and the glad hand box sits higher. Otherwise, definitely the kit trailer.
You did a nice job. I used to have the Revell version of this kit with the Mobilgas decals, but I never did build it. I knew it was small, but seeing the $20 bill really shows me just how small it really is.
