Roadmaster Guardian Rock ShieldThe Roadmaster Guardian rock shield is crafted from rotationally molded, high impact Polyethylene to absorb the impact of rocks, gravel, and road debris, instead of ricocheting it back to the motorhome. The Guardian rock shield can be attached and removed in seconds, and fits all Roadmaster tow bars equipped with Quick-disconnects. Can also be used with a tow dolly to help protect your towed vehicle by using Guardian bracket part number RM_2000-8. Roadmaster also offers a second vehicle kit with all the necessary hardware to to swap the Guardian from one vehicle to another. Initial Installation1. Remove the crossbar (Figure 1) and then the bolts holding the tow bar quick-disconnects (or, €œQDs,€ Figure1) to the tow bar mounting bracket (Figure 1). Then remove the safety plates (Figure1) and the tow bar quick-disconnects.2. There are two ways to attach the Guardian brackets, as shown in Figure 1: 1) Option A (with the thumb screws pointing toward the tow bar); or 2) Option B (with the thumb screws pointing away from the tow bar). Use Option A unless the Guardian will be within one inch or less of the towed vehicle €” if this is the case, use Option B.****CAUTION****The Guardian must not be closer than one inch from the bumper or any other part of the vehicle€™s body, or permanent damage to the towed vehicle€™s finish, as well as other consequential, non-warranty damagewill occur.3. Now, reattach the safety plates and the QDs with the Guardian mounting brackets between them, as shown in Figure 1. Use the original nuts and washers. However, do not use the original bolts €” use the supplied two-inch replacement bolts (Figure 1). Do not tighten any of the bolts €” leave them loose for now €” they will be tightened later. ****WARNING****€¢ Use the two-inch replacement bolts €” the original bolts are not long enough to compensate for the additional thickness of the Guardian mounting bracket.Unless the bolts thread completely through the nuts, the bolts will pull loose, causing the towed vehicle to separate from the motorhome.€¢ The safety plates (Figure 1) must be reinstalled. If the safety plates are not reinstalled, metal fatigue can cause a component of the quick-disconnectsystem to fail, causing the towed vehicle to separate from the motorhome.€¢ Use all mounting hardware, as shown in Figure 1. If all mounting hardware is not used, the quick-disconnect system will not support the weight of the towed vehicle,resulting in separation of the towed vehicle.Towing and Suspension SolutionsFailure to follow these instructions can cause property damage, personal injury or even death.4. The quick-disconnects must be centered on the tow bar mounting brackets (Figure 3). Adjust the quick-disconnects by sliding them to the left or the right, until they are centered over the tow bar mounting brackets.5. Now, test-fit the crossbar €” lower the crossbar over the quick-disconnects (Figure 2). The vertical pins at the top of both quick-disconnects should fit through the top holes at the ends of the crossbar (Figure 3), and the vertical pins at the bottom of the crossbar (Figure 3) should fitthrough the lower holes on the quick-disconnects. If necessary, adjust the quick-disconnects again, by moving them to the left or the right, until the crossbar slides on and off easily. If you must adjust the quick-disconnects a second time, make certain that they are both centered over the tow bar mounting brackets.6. Next, test-fit the Guardian center panel (Figure 4) €” the two posts (Figure 4) at the bottom of the center panel should fit into the Guardian mounting brackets (Figure 4). If necessary, slide the Guardian mounting brackets to the left or the right, until the center panel slides on and off easily.****CAUTION****Do not move the tow bar quick-disconnects in order to adjust the Guardian mounting brackets. The tow bar quick-disconnects must be centered on the tow bar mounting brackets. If they are attached too far to the left or the right, the tow bar will not be centered on the towed vehicle, which will cause excessive tirewear and/or other consequential, non-warranty damage. ****WARNING****Be certain that the tow bar brackets and quickdisconnects have been reassembled, according to the installation instructions, before towing. Incorrect assembly will cause the towing system to fail €” the towed vehicle will separate from the motorhome.Failure to follow these instructions can result in property loss, personal injury or even death.7. Now, torque the four replacement bolts to 75 ft./lbs. This completes the installation of the Guardian mounting hardware.  Features:
