You're limit will likely not be GCWR, but that 720 receiver limit or payload.
You need to verify the as equipped payload. Open the driver's door and locate this sticker on the door or jam. Note what is listed where mine says 2051:
Will you have 900 pounds of people and cargo inside the Jeep or is that your estimate for things you can pack in the RV too?
720 pound loaded TW means about 5500 pounds loaded, or 4500-5500 pounds dry.
