I've gone back through my Overwatch PBOs from December 2013, mainly the 2.5 version and it appears I never used towing/lifting on 2.5, but I did for 2.4 (in November 2013). 2.4 and 2.5 use different dayz code. So there is a possibility that R3F isn't compatible with 2.5. Not 100% sure so don't quote me. You can do some research in this forum and start asking around.
