I would GLADLY go back to a SRW, and if I was looking at the OPs trailer, I would wouldn't even look at the DRW - not needed, so why go to the hassle of owning one. Can't park it, doesn't fit in a car wash, typically doesn't fit in a garage, expensive to re-tire, and the list goes on. I towed with a SRW for over a decade and they are great tow machines. I'm only in a dually now because I'm up in the 4,000/17,000 lbs weight bracket with this trailer.
Don't let the tire blow outs scare you into thinking you need a dually. We all have single tires on the front, and that is the blow out that will send you off the road.
