I recently purchased a C-Max Energi for the purpose of towing all wheels down behind my motor home. The owners manual tells you how to set the car up for RV towing but nothing about what to use for assisted braking Now it seam I am having problems finding the right braking systems to place in the cabin since the energi also has regenerating brakes. Most state laws require assisted braking for vehicle being towed. I have talked to Ford dealer they have no clue and depending on what RV dealer they all have their own opinion. Has anyone set one up for RV towing? What brand are you using? dlan603
