Roadmaster provides different kits for adding a second towed vehicle versus preparing a second motorhome. Part 98160 installs vehicle-side BrakeMaster connections and BrakeAway; part 98200 provides motorhome-side hardware for a coach with air or air-over-hydraulic brakes. Neither is a complete supplemental braking system.

Confirm the correct braking system
The part-numbered items below identify components in the parent BrakeMaster system, not an independently verified box-by-box packing list for either transfer kit. Transfer the portable brake cylinder as directed by Roadmaster; the 98160 kit is not a second cylinder. The 98200 kit serves an air-brake motorhome and cannot be substituted for hydraulic-coach kit 98300.
