People need to look at there lifestyle as well as the weight of there trailer when trying to determine which truck will best suit there way of life. As an example , I like to hunt birds in the desert of Ca and Az and a drw is useless in the sand , and in the spring and fall we like to trout fish and often end up on narrow forest service roads where a dually doesnt fit , between that and the day to day driving in town a dually isnt ideal , in contrast if a guy is going to tow a trailer and spend alot of time traveling on the interstate , then a dually may be the best way to go .
My point is that the decision to get a drw or srw isnt black and white , and other things should factor into this decision.
