What are you planning on towing? The unit has a hitch rated at 5000 lbs and a seven pin electrical connector so you would seem to have everything you need.
What ever you are planning on towing should not exceed 4,220 lbs based on your GCWR of 15,250 lbs.
Also, if you are towing a trailer, the tongue weight of the trailer needs to be included in your GVWR of 11,030.
Perhaps you should start by weighing your unit to get the actual weigh with all your belongings aboard.
