I realize this thread is a year old but wanted to weigh in if someone else is searching. We own a Sabre TT and love it. The quality and floorplan is superior to most everything we looked at. Ours is the 31RLDS and has a dry ship weight of 8,000 lbs and over 11,000 lbs GVWR. In other words, it's rather heavy. I've had no trouble towing it with my Cummins powered '06 Ram 2500 or my '13 Ram 2500, both with factory hitches.
That said, I will never ever, ever, ever tow it on the highway again without the Reece Dual Cam sway control!!! Once was enough!
