We made several cross country trips with almost the same combination. Our trailer was 5300 dry (6500 on scale and packed). You will have to be a little concerned about the CCC on that trailer (not much...just be aware), and you will possibly get close on rear axle of the truck (I did).
The engine will pull it like nobodies business. The braking on long downhills in the Rockies will require skilled driving.
We added E rated tires and it was a noticeable improvement.
With a few minor things to be aware of, you will have a beautifully matched setup and tow about as easy as anything on the road.
