What is needed to use this dolly on a 2018 Thor ACE 30.3 I see it needs an electric brake controller. I have a 7 pin connector.

In order to use the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1 you'll need a few items such as a ball mount/hitch ball, trailer connector, and brake controller. The ball mount/hitch ball will be chosen based on your rise/drop needs but a good starting point is the Curt Towing Starter Kit part # C45534. If you need further help with this you can reference the help article I have attached below. It sounds like you already have a 7-way for the motorhome but you'll also need one for the tow dolly like the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector part # PK12706. Finally, you'll need a trailer brake controller for the motorhome and for this I recommend the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195.

It looks like the Thor ACE is built on a Ford F-53 Chassis which means you can add the Tekonsha Plug-In Wiring Adapter part # 3035-P for a plug-in play brake controller install.
