Towing question

I have a 2014 Ram Big Horn 4x4 eco diesel with 3:55 and am looking to purchase a travel trail weighing in around 6900-7000 lbs. it will be myself and my wife and two dogs traveling. We are wanting to travel to the National Parks across the US. I have read a couple of threads about others experiences and wanted to get some feedback on your thoughts about if I’d have the towing capacity.
