Thanks everyone for all the answers
First off, I have another question, but all of my questions from the original post has been solved
About the mod, I was talking about if I can buy the trailers, save the game and use the trailers in Truckersmp, so I will not use the mod in truckersmp and only use it to get the trailers
My second question is also been solved as you guys stated I can use the double trailers of the mod and my third question about the ban.
Now, I have another question. Can I use all of the trailers from the mod, even the heavy trailers (like the trains or the boats), but not the "special transport" trailers?
(About the heavy trailers: this is what Im talking about (if im sure that are these the heavy pack cargo)
Also, a heads up: these trailers have no aditional effect on the weight (they are just trailers with the cargo but with no additional weight (for example, if the cargo weighs 60 tons, it will only weight the platform/trailer)
