Dually trucks offer significant advantages over single rear wheel (SRW) trucks, primarily in stability and load capacity, making them ideal for towing heavy trailers like fifth wheels. The dual tires provide better blowout protection and hydroplaning resistance, enhancing safety during operation. However, duallys come with downsides, including decreased fuel efficiency, a rougher ride, and challenges in parking and maneuverability due to their wider stance. While some trucks are transitioning to super singles for better fuel efficiency, duals remain favored for their redundancy and lower wear in certain conditions. Ultimately, the choice between dually and SRW trucks depends on specific needs, especially for towing and off-road capabilities.

Off topic question i hope one of the truck guys may know. I think the answer is yes, but, do all dually's use a Full Floating Axle over a Semi-Floating Axle?

Based on my experience I would say yes. Haven't seen a truck with duals that wasn't floating.
