We found what may be a bug that is created when you have this mod running with CUP as part of a mission. We have had several instances of aircraft (Firewill A-10) that would just blow up as soon as we hooked them up with the tow tractor from cup using your towing mod. However when using CUP towing or Advanced towing in same mission they work as they should. I will try to get more information from the guys that did it but I wanted to post it here for you to at least be aware of it.
