@ChrisS that was my thought as well. Since you don't have factory wiring you can add a 4-way using the Curt # 55540. If you're wanting a 7-way the # ETBC7 has everything you need to upgrade to a 7-way from there.

Answer 1

Since your 2017 Ford F-150 is equipped with the factory trailer hitch, your only option for adding a new hitch is with the Curt Class IV Receiver Hitch #C14016. The 2" receiver on this Class IV hitch will sit just below the factory receiver.…

Hey Fred. The TowSmart Plug-In Trailer Connector Adapter - 4-Way Flat to 7-Blade item #TS74QR will need to be wired into factory wiring along with plugging into a 4-way connector. The TowSmart ProClass Trailer Connector - 4-Way to 7-Way and 4-Way…

Answer 9

Yes, the adapter part #HM47365 would work well for you based on your description of what you have. It sounds like you have a 7-way connector at the back of your 2011 Mercedes ML350 and a 4-way connector on your trailer. This adapter would convert the…

The spare tire retainer would almost certainly interfere with installing the #75210, but we do have a hitch that is positioned a bit differently so it would fit perfectly. The Curt #13250 class III hitch will avoid the spare tire retainer, as shown…

Hey Kim, thanks for reaching out. The Firestone Ride-Rite Air Bags with Easy Mount Compressor #F24XV do fit your 2020 Ram 2500 with rear coil springs, but the hang-up is the under-bed gooseneck hitch. On your truck, the air bag brackets and the…
