Hey Al, this is a great question. On the RViBrake 4 # RVI44FR, sensitivity is adjusted through the included Bullseye wireless monitor in the motorhome. The RVi4 and Bullseye first need to be paired. Then go into the RViBrake's settings on the Bullseye and select the Sensitivity setting, where you choose Normal or Panic Only.

There is a separate adjustment called Brake Pressure, and that's actually what you normally adjust if the towed vehicle seems to be braking too hard or too softly. This is probably what you are most interested in. With vacuum-assisted brakes, you select the appropriate vehicle size; with active-assisted brakes, you select the appropriate PSI. CURT then has you perform a brake test at about 30 mph and adjust pressure until activating the test produces only a gentle pull on the motorhome.
