Expert Reply:

Hi Jerry; you don't need a specific brake controller for the Roadmaster Tow Dolly # RM-2050-1. Any electric brake controller will work. My personal recommendation would be the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This brake controller is simple and reliable. The main unit installs behind the dash with only the control knob visible so it doesn't take up space in the cab. You will also need the # RED69FR for installation. There may be a custom wiring harness for your vehicle, but I can't check without knowing the year, make, and model.

I just purchased the dolly. It's a 2017 Roadmaster dolly. Vin 1V9CD1016HV089118. Hopefully this helps.

@JerryM the custom wiring harness would be for the tow vehicle. So something like a 2022 Ford F-350 or the same information for a motorhome. The brake controller installs in the vehicle towing the dolly so that information would be necessary to check for a wiring harness.

Will the #REDFR work with the 2017 Fleetwood Storm 34s motorhome?

@JerryM yes. If you have the factory tow package you can use the # C51322 along with the # 331-TPH-019 for a plug and play installation. If you do not have the factory tow package you will use the # RED69FR mentioned above.
