I think adding options for illegal trucking loads could actually create extra attention towards the job, especially from the crim side, and cops to combat the illegal truckers. It should be nice to have the option, illegal trucking happens all the time, the roleplay behind it is logical. It could also work very well with the current script, adding maybe 2-3 markers that are in more shady spots for where you can load up the trailer. If you really think about the big picture it could even add people guarding trucks in convoys if they feel like it, now imagine a convoy of crims battling cops over some illegal truckers. Sounds pretty fun, doesn't it?
