Stand with your feet together. Now have someone give you a shove from the side. Pick yourself up off the ground and try again, but this time stand with your feet shoulder-width apart. Still standing? That's the difference between an SRW and DRW on the road. Also, you have an extra tire on each side in case one fails and to spread the load more evenly between them.
In all seriousness, there is one more difference to consider between the two types of truck. The hub bearings on an SRW truck are often inboard of the rim. On a DRW, they're on the inboard and outboard sides, and the hub extends all the way through the center of both wheels and sticks out a bit. If you put a second rim onto a truck with a non hub-centric axle, you can snap your axle shaft under heavy loads, such as hitting a pothole while towing. It's hard to tell from your picture, but it looks as though your truck may already have the correct hubs on the rear.
