DRW vs. SRW for towing fivers

I had an 03 ram 3500 srw lb qc 4x4 cummins. I towed a cougar 320srx a 40' road warior and the fuzion in my sig. Not a bad tow but I wanted a newer truck with the 6.7 and the 6 speed trans. So I had an eye out and we went to Gettysburg for hallowen 2 weekend. We passed Beckleys and I saw 2 trucks that I liked and wanted to run back on friday to look at them. Of course Sandy came up the coast so brother and I got in his truck (3500 srw ram lb qc 4x4 cummins)and came back to the marina to haul boats with the crew Friday and Saturday. Saturday night left Rock Hall went back to Gettysburg to pick up his wife and kids, my wife and dog, the 2 5ers, B.J.,his family and rig. We left Gettysburg came down the road B.J. had a blow out. Changed his tire and got moving again. We hit the east bound span of the bay bridge and a gust hit me from the rear quarter and the truck started squirming. I was scared to death for the next 4 miles. Then we got home I unhooked,Did the whole storm thing!,winterized and bought the Dually from Beckleys with the 6.7 and the 6 speed auto. My brother didn't admit it to me but he told B.J. he got pushed around some that night too. B.J. said he was fine in his dually (lb cc 4x4 cummins). Of course he has a 32-35' cougar and brother has a 35'ish mountaineer. Get the dually or keep the dually.

P.S. Sorry for being so long winded in the story.
