89ft TOFC with 28ft Trailer Set Problem

Hello forum. Newbie here. Im having a small issue with which im wondering if someone can help me. Im running the Steam version of TS2015 build 52. something? I downloaded the TOFC set from the downloads page and got the parcel package as said in the installation instructions. I then put all the files into the folders and copied the ones I need to and installed them in the addons folders as the instructions said to do. I go to Quick Drive from the TS2015 menu and to build a custom consist. On the list under wagons the TOFC cars show up with no trailers. So I went to the TestTrak as its called in game to activate the boxes in the editor. Im now able to place the cars with trailers on the track (I still cant figure out how to make the consist I built drivable mind you).
My question is: Is there a way to set these up to be quick drive compatible with the trailers on them? I ask because I have an assortment of pre-made TOFC consists that I would like to insert these cars into to get rid of the default trailers, and to then be able to use these consists on whichever of my routes I choose.
Or have I done something completely wrong? Which is probably more than likely LOL.
Thanks in advance.
