Regenerative Braking while Flat Towing

[BigB]

I Flat Tow my Nissan Frontier with my Motorhome using a Blue Ox Patriot 3 Braking system. It uses a sensor on the dashboard to send a signal to a device in my truck that manually presses the brake pedal to Slow The Vehicle..

Wouldn't this charge the truck every time I hit the brakes? I really Want to Enhance the capability Of Regenerative charging While I tow it with my motorhome Period For example Using an app Let's say I wanted to add 10 percent Resistance To charge The slates battery or have an AI app that knows when to regenerate for example going downhill or just taking your foot off the gas Etc
