Theunz & BB_TX are right on.

I live in northern Canada and have owned both SRW and DRW 1 ton trucks. There is no question the dually has superior stability and load capacity, but traction.......doubtful.

Example: Two essentially identical trucks, same tires, no payload in the box. ...one a SRW, the other a DRW. Then drive each in snow under 2 wheel drive. The SRW has a far better chance than the DRW to get you anywhere. The DRW would be essentially useless with far less traction at the rear wheels.

We went the HDT route (Volvo 730) a few years ago and one of the main reasons was stopping power. We pull a 3790rd. When pulling it on interstates through cities (Denver, Salt Lake City), a couple near misses under panic stop conditions convinced us to go that route. Considering the weight of a 1 ton truck versus the weight of the trailers we run, it's never good when the tail wags the dog.
