Weight wise no issues as you have plenty of margin, and length wise you kept it very manageable for your tow vehicle. One of the biggest issues facing half-ton trucks towing TTs is dealing with rigs over 30' in length, heading down the road at interstate speeds can prove challenging at times.
Have a great time enjoying your new GD, although I like Jayco products I have always thought highly of GD rigs. I heard good things about their customer service, and that RK floorplan looks like a winner for your situation. Overall, a good truck/TT match, towing comfort should be good.
