I have added the templates for skinning the truck.  I use paint.net so all of the skins sit in one file. skin dds's are in the skins folder inside the mod.   
There are 4 skins with 5 dds per skin. i did it this way because if you wanted to get fancy with following of the sleeper lines 
and not get weird lines in the different skins showing up.
