You have it in the correct folder?

probably a mod conflict. If i had to guess its probably either a mod that has to do with a liquid production, better winch, or maybe a field service mod of some sort. those are the only ones i can think of that would cause an issue. try looking at the log file and search the rams mod folder name and see if an error comes up. if not try loading into the game with only the truck enabled.
