There are several ways to get unlimited money in American Truck Simulator. First off, you'll have to turn on console commands. This will require you to go to your DOCUMENTS folder on your computer and find the American Truck Simulator page. Then, you'll need to make a couple of changes to the in-game config file. With the console command now turned on, you can start using the unlimited money cheat. Now, open the console in-game, and type in: g_set_time x. This should skip ahead the in-game time to 12.00 am on the following day. As it's ticked over to a new day, you'll start receiving money based on how many drivers you have under your business. If that doesn't work as well, you might also consider installing unlimited money mods, too.
