This is the Bull version of my previous towtruck apparatus. Press 1 to flip if needed, and while one is on you can open the doors using the vtol handle. Here are the instructions from the last towtruck posting. Loading Instructions (before doing any step be sure that all your action groups are off unless the instruction says that multiple action groups have to be on, 5,6, and 7 are the lights and can be on during the procedure), take off 8 to stop the engine before doing anything on the mechanism, Press 2 with the VTOL handle all the way up to move the main line back (it will jerk sometimes, but it will continue sliding), now as the slide is coming back take off 2 ( it will continue moving and eventually stop. Now that 2 is off, press 4 with the trim lever all the way up, ( this will move back the secondary slide), once the secondary slide is out fully, take off 4, now there should be no action groups on (unless you are using the lights 6,5,7), now put the vtol handle all the way up and press 2, nothing should happen, now keep 2 on with the vtol handle all the way up, and put the trim up slowly to lower the back, just lower it enough so it is lightly touching the ground, next press 3 with the vtol handle slightly above the middle setting (this way your vehicle has a mild ramp edge to climb, do not extend the tailgate streight out for loading). Lastly drive your vehicle onto the bed, it may be a tight sqeeze with the tires, but it does work, any of my vehicles can fit and drive up onto it. CLOSING INSTRUCTIONS: Put the vtol handle all the way up when three is on to close the back. Take off 3, Put the vtol and trim handles to idle. Next press 4, then press 2. The slides should begin retracting. Once the slide is on the back of the truck, make sure that it fully slides under the holding brackets on the back of the cab. Now you can drive to your hearts content with a car on your back. (Or without one). If you need help take a look at some of the videos I have on everplay.
