Definitely disagree. A 33 ft. TT has a lot of real estate on each side. Acts like a big sail when there's high side winds. The only thing that counters that twisting/swaying motion brought on by high side winds is the sheer weight of the truck. The heavier the TV the more stability.
We've towed a few 30+ ft 8k-10k TT's with a 1/2-ton (5.5k weight) and 1-ton SRW truck (8.2k weight). The 1-ton SRW truck's almost 3k of additional weight brings a lot more stability to the table when there's high winds.
Lastly, even a trailer that only weighs 8k-10k could be handful for 1-ton SRW truck with a tow rating of 16k **IF** the side surface of the trailer is extremely high with high side winds. At some point excessive side surface area on a trailer can easily make the truck's tow rating completely moot.
