Do you have the tow package and 9k capacity? Seems odd a small TH would be near or over the GVWR of your Titan. My Armada has the same 5.6 with over 300 HP and almost 400 lbs. of torque. In the mountains it is a beast and I pull a 30 ft. trailer that is 6400 Lbs. loaded with about 900 on the tongue. In the NC Mountains I’m not winning any races but it pulls strong. How heavy is your 21 footer? You cannot have too much truck but seems your current vehicle would be up to the challenge of a smaller TH. The Titan/Armada has as much or more pulling power and capacity of any of the current ½ ton offerings so I agree if you’re not happy with the Titan a ¾ ton would be the way to go. Good luck!
