I have the updated 2005 version of your previous truck with a 9.8K lb GVWR and 23K lb GCWR. It hauls the the TC and pulls the trailer fine, but I would have chosen DRW if I had started without a truck to get a wider stance. After 10K miles of using this setup and a 5K mile trip coming up, I have tweaked the TV so I am comfortable towing and hauling with it (am looking forward to driving it the same route I pulled an 11K lb TH). We just returned to western side of the state from Moses Lake, WA hauling about 18.5K GCW without issues except for the poor performance of 19.5" wheels in the the sand/ash mix in the dunes.
