I noticed that all the SD60's, (the SD60M's are fine) kind of float on top of the track and derail very easily, not sure if you are aware of this. Again, thank you for the fun addons.
It's another mod pack all together, I selected the wrong one in-game. I did however download the Peterbilt 359,, all is well.
I miss read the pack name, I was referring to the anthem in the mack ar frame pack. My mistake
I have tried to attach them to the Mack Anthem complete pack trucks. Is there a trick to it?
