Trying to use the jeep dolly with the RGN trailer but I have tried everything and can't lock the jeep to the trailer (i can lock the truck to the jeep but nothing will lock the jeep to the trailer). Exportcommands and importcommands are both in the file and I've even parked a different truck next to the trailer to try and lock the kingping but it doesn't work (I can control other functions but nothing will get the trailer to lock to the jeep).
