A computerized control system for automating the process of connecting, d isconnecting and leveling a fifth wheel RV. This system replaces the manuall y operated up/down pushbutton switches that control the movement of the moto rized supports legs at the front of the RV. It is connected to the RVs batte ry and support legs motor. When it is time to disconnect the fifth wheel tow vehicle from the RV, the user presses the "Disconnect" button. The system a utomatically moves the RVs support legs down until it detects that the RV is at the disconnect position and then stops. The user can then disconnect the fifth wheel normally. When it is time to level the RV, the user presses the "Auto Level" button and the system automatically lowers the RV to a. level position. When it is time to reconnect the RV to the truck, the user presses the "Connect" button and the system automatically raises the RV back to the exact same height as before it was disconnected. After the RV and the truck have been connected, the final step is to fully retract the RV legs to trav el height. The user presses the "Retract" button which causes the system to raise the RV legs and then automatically stops when they have reached travel height. If the user needs to manually adjust the up/down position of the RV for any reason, the system has "Up" and "Down"buttons that provide the same functionality as the RVs up/down switches it replaced.
