I have that same truck. Mine is a 2014 with a complete tow package.
I tow a 5500 pound 25 foot long travel trailer, and my big fear with the amount of weight you will be towing is stopping on wet pavement.
I have had two different occasions where on wet pavement just crawling and then putting on the brakes both the truck and trailer skidded just as if I was on black ice due to the weight.
I consider myself a safe driver, and always take my foot off the gas and coast into traffic lights and cross roads, but on one of the occasions it was on a down hill and my rig skidded right into the middle of an intersection with the light against me.
So be forwarned !
