To wire your 2014 GMC Sierra 1500 so it's taillights operate in conjunction with those of the towing vehicle or Motorhome, you'll need a diode system like # RM-15267. The installation isn't too involved, as you can see in the install video I've linked for you.
You'll also need a few other items to flat tow your truck. Assuming you have a Roadmaster tow bar, the # RM-3177-1 base plates would work fine for you. You'll also need some safety cables like # RM-643, a supplemental braking system like # RM-9400, a stop lamp switch part # RM-751488 and a 12-volt outlet kit, part # RM-9332. If your installed base plate height has a greater height difference than 3 inches compared to the receiver on the tow vehicle, you'll also need a high/low adapter. I'll link you to an article that explains how to figure out if you need an adapter, and if so which one.
