I will have to post a picture of my blue superliner. I didn't like the sleeper option either so I just built a tunnel box to replace the space where the sleeper would have been totally changed the trucks whole look
Also not to be rude or picky but the body you have shown here is a new bodystyle 9055 which is the correct style body sides on today's rotators. However a 9055 isn't a rotator it's just a normal 50 ton wrecker. The repop rotator is bases off of an early challenger rotator. To be period correct you would use the older bodystyle 9055 body sides. You will know it is the correct one because the tail lights are not recessed in deep like the new style are.
