I dont often reply to any post however this Dually/srw debate has prompted my two cents . Let me first say , I am not trying to offend anyone or promote one over the other .
I live in the foothills east of San Diego right on interstate 8 where on every weekend from October through March , approximately 100,000 ,and sometimes more travel to the Glamis sand dunes,and at least 75% of them are towing some kind of trailer , and the greatest percentage are towing large Toyhaulers . I would say by observation that at least 80% of them are towed by srw trucks .I am talking trailers that are loaded to the gills and over 40 foot long , add this to the equation they have to go up and over one of the nastiest grades in this part of the country (6 to 7 percent)for 15 miles each way.Another thing to consider is this is a major trucking route to San Diego , so there is lots of semi traffic.
Just wanted to paint you all a picture of what goes on ....now as a result of all these illegal,irresponsible , life threatening individuals ...you rarely here or see any accidents,does this make right ? NO , I am not advocating that anyone tow with one truck over the other , what I am saying is that with a little common sense you can easily tow more than you think with an srw .My dad always told me to buy the truck for how you will use it 90% of the time, and he is right . If I were retired and was full time a dually might well be the way to go , short of that the new srw trucks are very capable . I have towed with both and in less than ideal conditions and both did the job well , and I felt no more worried in one over the other . In the wind the drw was more stable . In the end I guess it boils down to driving and towing experience . Have a great day
