Notes:
Install time: 3½ hours
- Trimming of spoiler, air dam, bumper, grill or plastic fascia may be required on some models of this vehicle.
- This is a direct-connect baseplate, to which any motorhome-mounted Roadmaster tow bar will attach. It neither uses nor will it accommodate Roadmaster's crossbar. As a result, there are no mounting points for Stowmaster tow bars, Guardians or Tow Defender part 4700. Tow Defender part #4750 will fit. In most cases, Roadmaster makes a crossbar version of this baseplate that will accommodate these products. Refer back to the fit guide to identify a crossbar version.

Footnotes:
- This vehicle has the equivalent of full-time, "active" brakes. Use only InvisiBrake or BrakeMaster. If using InvisiBrake, start the brake pressure at 20 psi and adjust up if additional braking force is desired. If using BrakeMaster, you will also need Brake Pressure Reducer #900002. Only use braking systems whose braking force can be significantly reduced to prevent vehicle brake damage.
3Brake Light Switch Kit
If the brake lights do not work with the towed vehicle's ignition key turned to the "tow" position, you need a brake light switch kit to provide a signal to the supplemental braking system. Roadmaster manufactures both vehicle-specific and universal brake light switch kits.
KIT NECESSARY:
4Fusemaster
If your vehicle drains the battery while towing, a FuseMaster can disconnect power to the fuses responsible for the drain.
FuseMaster Part(s):
- Not Applicable
5Seat Adapter
If you are installing a BrakeMaster supplemental braking system, you may need a seat adapter to mount it to your vehicle.
Note: The BrakeMaster mounting post is NOT included in the seat adapter kits.
