Question:

The C77MV trailer brake controller is listed as working on a 2023 thor chateau motorhome. I need to know if it will work on a 2025 thor chateau motorhome, it is on the Ford E350 chassis.

Hey Lance, I'm glad to hear the Curt Spectrum is a fit for your 2025 Thor Chateau. How did the installation go? I'm curious because your experience could really help others with similar setups.

@JamesonC The installation of the trailer brake controller went fairly well. Not much room to work under the dash of an E350 chassis. However, the wiring adaptor is not a direct plug and play. I had to repin 2 of the connections to get it to work properly. For some reason Ford configures the trailer brake harness plug differently on the E-series versus the F-series vehicles. After the minor rewire it all works great and I love the Curt spectrum controller. Easy controls. no big box hanging down getting in the way and easy to adjust.
