Yes, the Curt portable braking system for flat towing # RVI44FR is designed for both vacuum-assist and active electric or hydraulic brake systems, like those found on hybrids and EVs. Just make sure to select “Active Assist” in the Brake Type settings on your Bullseye display. From there, you can set your desired PSI starting around 5 PSI and use the Brake Test feature to dial it in. See attached photo for more info on this. :)

What type of motorhome do you have?
Also make sure to check out the owner's manual of your car, specficially the flat tow section.
