Best Brake Controller for Motorhome with Air Brakes Towing a Car Dolly

Expert Reply:

Although any of the Brake Controllers that we offer would work, I would recommend a proportional controller. A proportional controller can sense how quickly the tow vehicle is braking, and send enough voltage to the brakes on the dolly so that the vehicle and the tow dolly stop at the same rate. Our best selling proportional brake controller is the Tekonsha Prodigy, part number 90185. This controller would install on your motorhome just as it would on a vehicle with hydraulic brakes. If the motorhome doesn't already have a 7-way trailer connector, you will need a Hardwired Brake Controller Install Kit, part number ETBC7. This kit contains everything needed to install a brake controller on your vehicle. We have a Brake Controller Installation Guide, I will include a link to that and to the parts that I mentioned. You can find the links below.
