IMPORTANT: All braseplates must be assembled with all the bolts left loose for final adjustment and positioning (before
tightening) unless otherwise instructed. All bolts must be torqued for proper strength. If more than one bolt is used per
fastening point, the diagram may only show one.
• Use flat washers over all slotted holes • Use lock washers on all fasteners

Failure to follow these instructions
WARNING
• Installation of most baseplates requires moderate mechanical aptitude and skills. We strongly recommend professional installation by
an experienced installer.
• The installer must read the instructions and use all bolts and parts
supplied. Failure to do so could result in loss of the towed vehicle.
• Use Loctite® Red on all bolts used for mounting this bracket.
• Every 3,000 miles, the owner must inspect the fasteners for proper
torque, according to the bolt torque requirements chart on the last
page of these instructions. The owner must also inspect all mount-
ing points for cracks or other signs of fatigue every 3,000 miles.
Failure to do so could result in loss of the towed vehicle.
• The owner must check the vehicle manufacturer's instructions for
the proper procedure(s) to prepare the vehicle for towing. Some
vehicles must be equipped with a transmission lube pump, an axle
disconnect, driveline disconnect or free-wheeling hubs before they can
be towed. Failure to properly equip the vehicle will cause severe
damage to the transmission.
• If running changes were made by the vehicle manufacturer after this
kit was designed, some bolts or other fasteners in the hardware pack
may no longer be the correct size. It is the installer’s responsibility
to verify that the baseplate is securely fastened to the vehicle and fitted with the correct hardware to account for these changes. Failure to
securely fasten the baseplate could result in loss of the towed vehicle.
• If the towed vehicle has been in an accident, it must be properly repaired before attaching the baseplate. Do not install the baseplate if
any structural frame damage is found. Failure to repair the damage
could result in the loss of the towed vehicle.
can result in property damage,
personal injury or even death.
plate has removable arms, they must be removed before driving
the vehicle, unless the arms can be pinned or padlocked in place.
If not secured, the arms could vibrate out, resulting in non-warranty
damage or personal injury.
• Some motorhome chassis have such a tight turning radius that you can
damage your motorhome, towed vehicle, tow bar or baseplate while turning sharply. Before getting on the road, test your turning radius in
an empty parking lot. Turning too sharply could result in non-warranty
damage to towing system, motorhome and/or towed vehicle.
• Do not back up with the towed vehicle attached or non-warranty
damage will occur to your towing system, motorhome and/or towed
vehicle.
• The safety cables must connect the towing vehicle to the towed
vehicle frame to frame, with the cables crossed, with enough slack
for sharp turns. Refer to the cable instructions for proper routing.
Failure to leave enough slack in the safety cables, or failure to connect
the safety cables frame to frame, will result in the loss of the towed
vehicle.
• This kit is designed for use with ROADMASTER tow bars and ROADMASTER adaptors only. Using this kit with other brands, without
an approved ROADMASTER adaptor, may result in non-warranty
damage or injury.
• Do not use this document for custom fabrication, as it may not show
all parts or structural components. Custom fabrication, or any attempt
to copy this baseplate design, could result in loss of the towed vehicle.
• Upon final installation, the installer must inspect the baseplate to
ensure adequate clearance, particularly around hoses, air conditioner lines, radiators, etc., or non-warranty damage to the towed
vehicle will result.
• This baseplate is only warranteed for the original installation. Installing a used baseplate on another vehicle is not recommended and
will void the warranty.
