Mac Curtainsiders v1.0.0.0

This is my pack of Mac Curtainsider trailers.  The trailers come in 20', 40' and 53' with MANY different axle configurations. The axles will slide with mouse controls, and the kingpin is slightly adjustable with mouse controls as well. Drop axles can be raised or lowered using the fold function. The curtains and the rear door can be opened and closed using mouse controls. This mod, like most of my mods is a WIP. It is a bit messy and I add stuff as I think of them and I am constantly tweaking and updating it. As always, let me know if you have any suggestions or feedback.
