If you are flat-towing your 2014 GMC Acadia behind your 2015 Fleetwood there are 5 things you will need. You will need base plates for the Acadia, a tow bar, safety cables, wiring for the Acadia for lights, and most states now require a supplemental brake system.

First I recommend the Roadmaster EZ Base Plate Kit, part # 523149-1. With the hidden brackets, these are virtually invisible when the drawbars are removed.

The tow bar I recommend is the RoadMaster Falcon 2 Tow Bar, part # RM-520. This has a quick-disconnect system that lets you easily mount and remove the tow bar.

For safety cables I recommend part # RM-643. These are vinyl-coated coiled cables that help for ground clearance and have a heavy-duty steel hook with spring-loaded latches.

For tail light wiring when flat-towing your Acadia I recommend the Roadmaster Tow Bar Wiring, part # RM-154. When using this system I recommend using fuse bypasses so you do not have to remove the fuses from the fuse holder on your vehicle.

Since you need to remove bypass 3 fuses when flat-towing I recommend part # RM-76517 for one fuse and part # RM76514 for the remaining 2 fuses. These will allow you to just flip the switch from normal to the tow position to override the fuses and you are good to go.

For supplemental brakes I recommend part # RM-9400. this is a proportional system that applies the brakes on your Acadia when you press the brakes on your RV.

A couple of other items I recommend when flat-towing is a stop light switch like part # RM-751221. This activates the monitoring system in the RV to let you know when the brakes in your Acadia are being applied.

I also recommend part # RM-9332. This will connect to the towed vehicles battery and provide power for the braking system.

I have attached links to some helpful articles about flat-towing you can take a look at.
