Pro tipSupplemental braking: what to know

  • Often required by law. Most U.S. states and Canadian provinces require brakes on a towed vehicle above a certain weight, and towing equipment makers generally expect one.
  • Match your motorhome. Some systems are designed for coaches with air brakes and others for hydraulic brakes — check which your RV has.
  • Portable vs. permanently installed. Portable units move between cars; installed systems are quicker to hook up day to day.
