I can at least tell you some of the basics for ROR. You can find tracks and maps in the download section of Sim Monsters. Most trucks/tracks come in the forms of mediafire links (just close out of any ads that pop up). When the zip file is downloaded, go to your documents folder, there should be a Rigs of Rods folder in there. You can drag all truck zip files into the vehicles folder and drag all tracks into the terrains folder, or some people put all of their zip files in the packs folder, but I prefer the other method. since you have the latest version, to spawn a truck, you drag your cursor to the upper left hand corner of the screen, go to vehicles, and select "Get new vehicle." The basic controls for keyboard are the arrow keys to accelerate, braking, and front steering. You can press Q to change your shifting from automatic to manual. You can press A to shift up and Z to shift down.If you have a numpad, you can change your camera angle, or right click and drag and use the mouse wheel to change it. You can use backspace to respawn your truck from your current location or i to respawn it completely from the original spawn point. If you have any questions, feel free to post them in the Help and Support thread, and I hope you have fun in both the ROR and Beam communities
EDIT: A few other controls to note are the following: you can press enter on your keyboard to leave/enter your truck, you can press P to enable the parking brake, to hide the HUD (Which has the speedometer and other stuff covering the screen), you can press U, if your truck stalls, hold S for like a second and it'll re-fire, and to shut the truck off completely, you can press X, and to turn it back on, press X then S. Also, you can use F1 and F2 for rear steering which is something important I forgot to mention, lol. If F1 and F2 don't work then you might have to hold the fn key if your keyboard has it then press F1 or F2, that should pretty much cover it now
