I just bought a Ford C-Max Hybrid which is towable 4 down.
Note that the Blue Ox Patriot brake needs to be reprogramed for a hybrid & can't be set higher than 3. Blue Ox website has programming instructions.
I intend to install a charge line with a cigarette lighter end in the car to power the Patriot & not involve the hybrid's electrical system.
